PROBLEM TO BE SOLVED: To prevent a metal fitting from being deformed and damaged by preventing a button-shaped battery from hitting the metal fitting to fix the battery, and to prevent the battery from dropping off by impact. SOLUTION: The button-shaped battery 1 is obliquely inserted between housings 4b, 4c, and also between the lower sides of fixed housings 8b, 8c and the bottom surface of the battery holder 2, from the upper part of a stopper 9. Accordingly, the fixed housings 8a-8d receive no pressing force from the button-shaped battery 1 when the button-shaped battery 1 is inserted, and they have therefore no chance of being deformed. If the button-shaped battery 1 is stored in the battery holder 2, the button-shaped battery 1 is prevented from dropping upward by the fixed housings 8a-8d, and is prevented from laterally dropping by the housings 4a-4f and the stopper 9 in order to keep its fixed condition. Since the lengths of the fixed housings 8a-8d can be lengthened, the battery can be prevented from dropping by impact.
