Abstract
A battery pack includes: a plurality of battery cells arranged side by side along a first direction; and a case having an inner space for accommodating the plurality of battery cells. The case includes a first member, a second member that forms the inner space together with the first member, and a sealing portion that seals a joining portion between the first member and the second member. The first member has a first portion in abutment with the sealing portion. The second member has a second portion facing the first portion with the sealing portion being interposed between the second portion and the first portion. When an expansion pressure of the inner space acts on the case, a force in a shearing direction acts on the sealing portion sandwiched between the first portion and the second portion.
