Abstract

Provided are flexible heater excellent in heat resistance and in terminal strength, and a method for manufacturing same. A flexible heater 2 includes: a based member 10 made of multilayer polyimide film having a thermally-fusible polyimide surface layer on at least one surface thereof; a heating element circuit 12 formed on the thermally-fusible polyimide surface layer of the base member 10; a heating element circuit cover member 14 which is made of a multilayer polyimide film having thermally-fusible polyimide surface layers on both surfaces thereof and covers the heating element circuit 12; and a pair of lead wires 17 and 17 connected to a pair of connection end portions 12a and 12a of heating element circuit 12. The heating element circuit cover member 14 has opened portions 14a and 14a so as not to cover connection end portions 12a and 12a and their surroundings. The connection end portions 12a and 12a and their surroundings, and portions of the lead wires 17 and 17 above the base member 10 are covered through a heat-resistant adhesive 20 with an end portion cover member 22 which is provided separately from heating element circuit cover member 14 and made of a multilayer polyimide film having a thermally-fusible polyimide surface layer on at least one surface thereof.
