PROBLEM TO BE SOLVED: To effectively prevent the peeling off of a lead plate with respect to shocks without deterioration in electrical performance by connecting one end of a lead plate, folding back the middle part to form a cushion deforming part, and connecting the other end to a printed circuit board without mechanically fixing a battery to the printed circuit board. SOLUTION: A battery 3 is a thin square battery and is not mechanically fixed to a printed circuit board 1 by means of adhesion or the like. The battery 3 is connected to a printed circuit board via a lead plate 4, and inserted into a case to be set in the specified position. One end of the lead plate 4 is connected to the battery, the middle part of it is folded back to form a cushion deforming part 4A, and the other end is connected to the printed circuit board 1. The cushion deforming part 4A is formed by being folded back at the middle part connected to between the battery 3 and the printed circuit board 1 and extended, so as to be capable of being easily deformed, and absorbs stressed generated, when the battery 3 and the printed circuit board 1 are moved relatively from receiving the shock applied to the battery. |
