<p>The problem is to be able to maintain an electrical connection even when solder is lost. In the battery pack, the printed circuit board 12 has a PCB hole 13 to solder a lead plate 11, and the circumferential edge of the PCB hole 13 has a conductive pattern 15 formed to connect conductively to the lead plate 11. The battery holder 23 has a positioning mechanism holding a lead plate 11 in a position corresponding to the PCB hole 13, and a fixing mechanism arranging the printed circuit board 12 on the lead plate 11 positioned on the battery holder 23 by the positioning mechanism in a state making contact with the conductive pattern 15, and fixing the lead plate 11 to the battery holder 23 in this state. The printed circuit board 12 is fixed to the battery holder 23 by the fixing mechanism in a state having pressure applied to the printed circuit board 12 by the lead plate 11, and the lead plate 11 is soldered to the printed circuit board 12 via the PCB hole 13 in this state.</p> |
