Abstract: In a battery pack, a battery core pack is housed in an outer case where a gas discharge hole is closed by a breathable waterproof sheet, a design sheet is disposed to cover the breathable waterproof sheet, a gas groove is provided between the breathable waterproof sheet and the design sheet, and the gas groove communicates with a discharge side of the breathable waterproof sheet.

Abstract: 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.

Abstract: A battery pack includes a plurality of secondary battery cells, a battery holder, a circuit substrate, and an outer case, in which the battery holder is divided into a plurality of divided holders, each of the divided holders forms a fitting structure for fitting the divided holders to each other at an interface for joining the divided holders together, the battery holder forms a substrate holding area that holds a circuit substrate with the circuit substrate surrounded by side walls in a state where the divided holders are coupled to each other by the fitting structure, a joint interface where the divided holders are fitted to each other by the fitting structure of the divided holders is exposed in the substrate holding area, and a surface of the circuit substrate is covered with a potting resin in the substrate holding area.
