摘要： A battery pack includes a battery assembly, a heat radiation molding being molded in advance and having flexibility, and an external case housing the battery assembly. The battery assembly includes at least one secondary battery cell and a battery holder to hold and house the at least one secondary battery cell. A heat radiation molding covers a surface of the at least one secondary battery cell and is designed to melt in response to heat generated from the at least one secondary battery cell.
