具８′に接続させている。(b) Conventional technology As a conventional thin lead-acid battery, for example,
-159162, and FIG. 9 shows a schematic diagram of a battery that is substantially similar to the technology disclosed in the publication. In this figure, 1' is a battery case, 2', 3' are current collectors, 4',
5' is an electrode plate, 6' is a separator, and 8', 8' are rivet metal fittings serving as terminals. and the terminal 8',
8' and current collectors 2' and 3' are connected by lead wires 9'. However, in this terminal connection method, there is a possibility that the lead wire 9' may be corroded by the electrolytic solution, ie, sulfuric acid, impregnated in the separator 6' or the electrode plates 3', 4' and may be cut. Therefore, a through hole 10' is formed in the battery case 1', and the lead wire 9' connected to the current collector 2' is led out through the through hole 10'. It is connected to the rivet metal fitting 8'.

た。 In this case, the connection between the current collector 2' and the lead wire 9',
Connection with the rivet fitting 8' is made by soldering. Therefore, the current collector 2', the lead wire 9', or the battery case 1' may be damaged by the heat of the solder. Also, when the lead wire 9' was taken out of the battery case, epoxy resin was used to seal the extraction part, but there was enough space to fill the extraction part with enough epoxy resin to completely seal the extraction part. There is no
Therefore, it was likely that liquid would leak from that part.

め端子の熱損も起る可能性がある。 Further, the terminal is rod-shaped like a rivet fitting 8' shown in FIG. 10, and it is difficult to fix this terminal always perpendicular to the plane of the battery case 1'. If it is even slightly inclined, contact with the power receiving terminal of the electrical device is likely to be incomplete. Moreover, since the rivet metal fitting 8' and the lead wire 9' are connected by soldering, there is a possibility that heat loss of the terminals may occur.
