Abstract
Noise generated by driving a relay provided on a battery pack is suppressed. A negative relay is fixed onto top of a bottom face and an inner side surface of a lower case of the battery pack via multiple mounting points formed on an L-shaped fixture. The center of gravity of the negative relay is located within a polygon having the mounting points as vertices.
