Abstract: An electrical apparatus comprises an extension portion extending in a direction that intersects the direction in which a battery attachment surface of a battery base extends. A battery includes a plurality of battery cells with negative electrode side end faces. The battery has negative electrode side holding portions adjacent to the exterior of each of the negative electrode side end faces. The negative electrode side holding portions are located closer to the inner region of the center of gravity of the apparatus than a virtual plane to which a lateral rear side of the extension portion and a lateral rear side of the battery are tangent.
