A small battery box, in which arrangement of cells can be easily changed, for suppressing nonuniformity in temperature distribution between the cells. The box has a container having upper, lower, front, rear, and side portions which can be disassembled; a battery holder having members which are detachably connected in a manner such that central axes of the cells are parallel to a direction along which the side portions face each other and the cells are arranged in a zig-zag matrix form; a shielding member, near a coolant supply opening in the front portion, for changing the flow direction of the coolant and for preventing the coolant from directly blowing onto the cells; and a control member, near a coolant discharge opening in the rear portion, for changing the coolant flow direction in a manner such that the coolant flows towards the rear side of each cell near the discharge opening.
