PURPOSE: To eliminate necessity for a battery holder also to be able to easily sort a battery disused, by providing continued holes in the periphery of a battery mounting position of a printed circuit board, and directly soldering the battery to the circuit board. CONSTITUTION: Continued holes 2-5 are arranged in a manner of separating a part where a battery 2-2 is soldered from that except this part, on a printed circuit board 2-1. In this way, a part separated by a groove 2-6 in the board 2-1 is bent along this holes 2-5, so that the battery 2-2 can be easily separated from the board 2-1. Accordingly, a cost is reduced, also to perform sorting the battery and the other parts to collect refuse. |
