A method for producing a flavor component-containing liquid for use in a flavor inhaler that generates an aerosol, the flavor component-containing liquid comprising an aerosol source and a flavor component derived from a tobacco material, and the flavor component-containing liquid being converted to the aerosol by the flavor inhaler, wherein the method comprises: heating the tobacco material at a temperature of the tobacco material within the range of 80-100°C to thereby reduce the water content of the tobacco material; heating the tobacco material with the reduced water content at a temperature of the tobacco material higher than 100°C to thereby vaporize a high-boiling-point flavor component from the tobacco material; and dissolving the vaporized high-boiling-point flavor component in a liquid serving as at least a portion of the aerosol source to thereby obtain a high-boiling-point flavor component-containing liquid.

The present invention provides a method for treating a tobacco raw material, which enables a reduction in the amount of furan analogs contained in smoke which is generated when the tobacco raw material is heated. A method for treating a tobacco raw material, the method comprising: a step of preparing a tobacco raw material having a pH of 8 or greater by adding a basic substance to a tobacco raw material; and a step of heating the tobacco raw material having a pH of 8 or greater until the pH reaches 6.3 or less.

A non-combustion flavor inhalation article comprises: a tip-end plug; a tobacco segment provided downstream of the tip-end plug; a cooling segment provided downstream of the tobacco segment; and a mouthpiece segment provided downstream of the cooling segment. The tip-end plug comprises: a tip-end plug filler material; a sheet-like first wrapper covering the outer circumference of the tip-end plug filler material; and a first seam portion which is provided along a longitudinal direction of the flavor inhalation article at an overlap part between end portions of the first wrapper, has a region afforded by a water-based adhesive, and fixes the overlap part of the first wrapper. A hot-melt adhesive which is melted by heating is not used at the first seam portion.

A rod portion for a flavor inhalation article comprises: a filler material; a wrapper which is formed into a sheet shape and covers the outer circumference of the filler material; and a seam portion for fixing an overlap part of the wrapper. The seam portion is provided along an axial direction of the rod portion at the overlap part between end portions of the wrapper, comprises a first region afforded by a water-based adhesive and a second region afforded by a water-based adhesive and provided adjacent to a circumferential outer side of the first region at the overlap part of the wrapper, and fixes the overlap part of the wrapper. A hot-melt adhesive which is melted by heating is then not used at the seam portion.

An aerosol-generating device comprising: a heating unit for heating an aerosol source; a memory for recording an operation log; a first constant voltage circuit for generating an operating power supply of the memory; a temperature sensor for measuring a temperature change at a measurement site that accompanies heating by the heating unit; an AD conversion circuit for converting an output voltage of the temperature sensor to digital data; a second constant voltage circuit for generating a reference voltage supplied to the AD conversion circuit; and a control unit for stopping heating by the heating unit when the output voltage of the temperature sensor exceeds a threshold, wherein a potential of the operating power supply of the memory and a potential of the reference voltage are the same.

This aerosol generation device comprises: a heating unit that heats a substrate which includes an aerosol source; a control unit that controls the heating carried out by the heating unit; a power supply unit that supplies power-supply power to the control unit; and an output unit that outputs a low signal to the control unit through a connection signal line if there is connection with an external device. The power supply unit is connected to the connection signal line via a resistor.

An aerosol-generating device is provided with: a heating unit for heating an aerosol source; a notification unit for notifying a user of information relating to heating of the aerosol source; a control unit for controlling operation of the notification unit; a control element which is controlled by the control unit and opens/closes an electrical connection of the notification unit; a first power supply for supplying power to the control unit; a second power supply for supplying power to the notification unit; and a first switch which controls power supply from the second power supply to the notification unit by using power supplied from the first power supply as an enable signal.
