薄型の特長を活用することができない。<Problems to be Solved by the Invention> By the way, two or three card batteries are connected in series and built into a card-shaped device such as an IC card or a memory card. The connections between each card battery are as follows:
Generally, crimp terminals or pull-out lead wires are used, but
Both connection means have the following drawbacks. In other words, when using crimp terminals, the opposite electrode plates of two card batteries to be connected are overlapped and the crimp terminals are used to sandwich and press them together so that they do not come apart, so the connection part becomes thick and the card batteries It is not possible to take advantage of its own ultra-thin feature.

りバッテリ本体部１に悪影響を与える問題がある。On the other hand, when using lead wires, the lead wires are drawn out and connected by soldering, so it is necessary to apply a treatment such as nickel plating to the electrode plate for soldering, which increases the cost. Furthermore, it is necessary to use a sealing material that is heat resistant and does not melt against the solder, which narrows the range of sealing material selections, which also increases costs. Furthermore, soldering sometimes has the problem of adversely affecting the battery main body 1 due to the heat generated.
