A flavor-generating article, which is heated by means of a heat-not-burn flavor inhaler to generate a flavor, comprises: a first end inserted into the flavor inhaler; a second end on the opposite side to the first end; a flavor-generating segment containing a flavor source; a first segment disposed on the first end side of the flavor-generating segment; and a second segment which has a filter and is disposed on the second end side of the flavor-generating segment, a space in the first segment enabling communication between the first end side and the second end side of the first segment is filled with a first filler material, and the airflow resistance per segment of the first segment is higher than the airflow resistance per segment of the second segment.

A flavor-generating article comprises a flavor source and an upstream portion disposed on an upstream side of the flavor source. The upstream portion has a first part, and a second part with a lower void ratio than the first part. The first part and the second part are adjacently arranged in a cross section orthogonal to a direction of adjacency of the flavor source and the upstream portion.

A flavor-generating article is provided. This flavor-generating article is at least partially accommodated in a flavor inhaler and comprises a flavor source which is heated to generate a flavor, the flavor source has a first part which overlaps a heater of the flavor inhaler in a longitudinal direction of the flavor-generating article, and a second part which does not overlap the heater of the flavor inhaler when the flavor-generating article is accommodated at the desired location in the flavor inhaler, and the longitudinal length of the first part is between 40% and 61% of the longitudinal length of the flavor source and is also 10 mm or less.

A flavor-generating article comprises: a first rod portion including at least a flavor-generating portion; a first wrapper covering the first rod portion; and an adhesive for bonding the first wrapper to the first rod portion. The adhesive is provided over the entire circumference of at least part of the flavor-generating portion in a longitudinal direction thereof and is provided on at least 50% of a contact area between the flavor-generating portion and the first wrapper.

A flavor-generating article comprises: a first rod portion including a flavor source and a first wrapper covering the periphery of the flavor source; an upstream portion disposed upstream of the first rod portion; a second wrapper covering the periphery of the first rod portion and the upstream portion; and a first bonding portion for bonding the first wrapper and the second wrapper. The second wrapper covers the entire periphery of the first wrapper.

PROBLEM: To further improve user convenience while ensuring the correctness of authentication performed using biometric information. SOLUTION: An aerosol-generating device comprising: a biosensor for acquiring biometric information of a user; a communication unit for sending the biometric information to a server and for receiving, from the server, association information indicating that the biometric information which was sent is associated with personal information of the user stored in the server; an authentication unit for authenticating the user by matching the biometric information of the user authenticated by the association information with the biometric information acquired by the biosensor; and a device control unit for unlocking an aerosol-generating function when the user has been successfully authenticated.

An inhalation device (100) constituting an example of an aerosol-generating device comprises: an accommodating portion (140) which has an opening (142) at one end and accommodates at least a portion of a stick-type substrate (150) inserted through the opening (142); a pressure sensor for outputting a value relating to pressure which is generated as a result of the stick-type substrate (150) being inserted into the accommodating portion (140); a heating unit (121) for heating the stick-type substrate (150) accommodated in the accommodating portion (140); and a control unit (116) for controlling heating by the heating unit (121) based on an output value of the pressure sensor. The control unit (116) performs heating by means of the heating unit (121) when the output value at the time the stick-type substrate (150) was inserted into the accommodating portion (140) is included in a first range, and does not perform heating by means of the heating unit (121) when said output value is included in a second range different from the first range.
