Abstract
A battery pack includes a plurality of battery cells stacked together, and a case that accommodates the battery cells. The battery cells include an endmost cell disposed at a farthest end on one side in a stacking direction, a first cell disposed adjacent to the endmost cell, and a second cell disposed adjacent to the first cell. Further, the case is configured such that a thermal resistance between an endmost contact portion that is a portion in contact with the endmost cell and a first contact portion that is a portion in contact with the first cell is higher than a thermal resistance between a second contact portion that is a portion in contact with the second cell and the first contact portion.
