METHOD OF MANUFACTURING FILM-ARMORED ELECTRIC DEVICE, HEATER, AND FILM-ARMORED ELECTRIC DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a method of manufacturing a film-armored electric device capable of surely executing thermal adhesion in the vicinity of an electrode terminal, to provide a heater, and to provide a film-armored electric device. PSOLUTION: This method of manufacturing the film-armored electric device includes processes of: coating a lead terminal 4 with sealants 11 each having an extension part 11c having a surface pressingly extending a thermally-adhesive resin layer by jointing the sealants 11 to each other and pressing them; and executing thermal adhesion by using heaters 50a and 50b having a peripheral heating part 52 for thermally welding laminate films 5 and 6 in a peripheral part of a battery element 2, a lead heating part 51 for thermally welding the sealant 11 corresponding to the lead terminal 4 and formed into a recessed shape with respect to the peripheral heating part 52 to the laminate films 5 and 6, and an intermediate heating part 53 connecting the peripheral heating part 52 to the lead heating part 51 in a step-like form for thermally welding the extension part 11c of the sealant 11 to the laminate films 5 and 6.
