BATTERY PACK AND ELECTRICAL EQUIPMENT

Provided is a battery pack which is miniaturized by reducing the number of components of a latch mechanism of the battery pack. In the battery pack comprising housings (101, 110) that accommodate a plurality of battery cells (106), and detachable latches (160, 170), the latches have manipulation parts (161, 171) that are manipulated by an operator, springs (167, 177) that bias the manipulation parts to the outside of the housings, and first abutting parts (163, 173) on which ends of the springs abut. The manipulation parts move horizontally below the upper wall of the housing (110), and portions thereof are exposed to the outside from through holes (126a, 126b) formed in the housing. Furthermore, the latches are supported from below by any one among a separator (150) holding the battery cell, a circuit board (130), and a lower case (101).
