And the length of the first printed circuit board 30 are the same as the length of the battery 20. If the total length of these is longer, the length of the main body case 10 has to be adjusted to this total length, and the case becomes large, and when bending the lead plate described later, Since it has to be bent at an acute angle, extra stress is applied to the lead plate. On the other hand, if the total length is shorter, there is a risk that the lead plate may come into contact with the outer can 21, or there is a problem that the exposed portion of the lead plate requires further insulation. Therefore, these problems are solved by making the total length exactly the same as the length of the battery 20 as in the present embodiment.

The printed circuit board 30 and the second printed circuit board 31 are connected. The second lead plate 41 connects the second printed board 31 and the battery outer can 21. By these lead plates, the thermistor 35 and the first printed circuit board 30 are arranged along the side surface in the longitudinal direction of the battery 20, and the second printed circuit board 32 is arranged along the side surface in the lateral direction. .
Then, the second lead plate 41 is further bent and the first lead plate 41 is bent.

If the opposite ends of both substrates are separated without overlapping, the bent portion of the first lead plate 40 will come into contact with the outer can 21 when there is some space in the length of the lead plate. There is danger. Since the first lead plate 40 is electrically connected to the electrode cap 22, if it comes into contact with the outer can 21, it will be short-circuited. Therefore, short-circuiting due to the lead plate is prevented by overlapping the ends of both the substrates.
