The present invention relates to a thin battery having a structure in which a thermoplastic resin is placed and hermetically sealed by thermocompression bonding.

。(b) Conventional technology This type of battery used as a power source for card calculators and IC card memory packs has a thickness of 0.5 m.
It is required to be as thin as 300 m and have repeatable bendability.

脂である。Due to these difficulties, thin metal plates are used as the exterior body, but as shown in Figure 2, they tend to wrinkle as the number of times they are used.
There is a concern that leakage may occur due to leakage or bending. Note that in FIG. 2, the outer shell is made of a thin metal plate and serves as a terminal, and the outer shell is an insulating heat-adhesive resin.

性が得られず、封口邪において外装体と絶縁性の熱＠着
性樹脂との間で剥れなどの不良が生じる。Therefore, for example, as disclosed in JP-A-60-195873 or JP-A-60-195874, the metal exterior body that also serves as a terminal is pre-sintered to soften the exterior body and make it thin. It has been proposed to impart flexibility to batteries. However, even if such a sintered metal exterior body is used, sufficient reliability cannot be obtained due to repeated bending, and problems such as peeling between the exterior body and the insulating heat-adhesive resin may occur during sealing. Defects occur.

ある場合にはその効果はさらに増大する。(Using a 4-electroelectric resin film as the exterior body for stimulation has superior repeatability in bending compared to the conventional case of using a gold-layer thin plate, and since the resins are bonded to each other at the sealing part, As such, a stronger bonding force is obtained and the sealing performance is improved compared to the bonding between a thin metal plate and a resin.Especially when the thermoadhesive resin and the resin constituting the conductive resin film are the same type of resin. The effect will further increase.
