PROBLEM TO BE SOLVED: To reliably prevent problems due to rain water such as short circuits with a simple structure even if the rain water intrudes into a charging connector, and to reliably prevent the rain water from intruding from the charging connector with a simple structure.SOLUTION: The battery pack includes an exterior case 40 connecting multiple batteries 1 in series and in parallel and housing the multiple batteries and a charging connector 70 provided at the exterior case 40 and charging the built-in batteries 1. The charging connector 70 is arranged on a side surface of the exterior case 40. Further, a terminal insertion portion 70A of the charging connector 70 is arranged so as to face downward relative to the horizontal direction by utilizing the side surface as an undercut surface 52 which approaches an opposing surface in the downward direction.
