が提案されている。[0003] As the configuration of this small secondary battery, a cylindrical battery in which wound electrode groups are housed in a cylindrical metal case or a square battery in which flat electrode plates are stacked and housed in a rectangular metal case are used. is there. As means for providing a cheaper and lighter small secondary battery, for example, in Japanese Utility Model Application Laid-Open No. 60-162362 and Japanese Patent Application Laid-Open No. 61-206157, a power generating element is housed in a bag of an aluminum laminated film and sealed by heat welding. Things have been suggested.

結合したものが示されている。Further, since the exterior of the laminate film, especially the thin portion which is the sealing portion around the battery is weak against external force and easily deformed, some measures such as using an exterior container have been devised.
Japanese Utility Model Publication No. Sho 63-42462 discloses a battery in which a frame fitted to a battery thick portion is joined to a battery thin portion which is a joint portion of an exterior film.

る。However, the use of an outer container impairs the advantages of high energy density and low manufacturing cost of a battery using a film for the outer package. In addition, when the frame is joined only to the thin portion of the battery, the joint between the frame and the battery is easily exposed to an external impact, which causes the battery to peel off. Furthermore, attaching the frame to the battery sealed with the exterior film is a secondary process that is a post-process, and therefore requires additional steps.

May cause a short circuit.
Further, it is difficult to select the thickness and strength of the lead terminal material. That is, since a certain strength is required for the lead terminal, a material having a small thickness cannot be selected. However, if a thick material is used, it becomes difficult to secure the sealing property of the portion of the sealing film of the exterior film that the lead terminal crosses. Further, attaching the lead terminal requires a material cost and processing man-hour for it.
