In FIG. 1, reference numeral 11 denotes a case made of plastic. As shown in FIG. 2, the case 11 as a whole is formed in a thin plate shape, and is configured to accommodate a plurality of batteries 12 inside.
【００１１】 また、ケース１１の端部（図中左側）は、図示しない電気機器及び充電用機器 等と嵌合可能なように、段差状に形成されており、ここに、導電性部材として、 所定形状に形成された金属板１３が配置されている。そして、この金属板１３に よって、充電用の外部接続用電極１４ａ、放電用の外部接続用電極１４ｂ、電池 用電極１４ｃが形成されている。これらの電極のうち、電池用電極１４ｃは、ケ ース１１内に位置し、充電用の外部接続用電極１４ａ、放電用の外部接続用電極 １４ｂは、外部に露出するよう配置されている。In addition, an end portion (left side in the drawing) of the case 11 is formed in a stepped shape so that it can be fitted with an electric device, a charging device, and the like (not shown). Here, as a conductive member, A metal plate 13 formed in a predetermined shape is arranged.
