A battery pack includes a plurality of laminated cells stacked in a first direction of a horizontal direction, and a battery case accommodating the plurality of laminated cells. Each of the laminated cells includes a cell body portion, and a cell terminal extending from the cell body portion in a second direction orthogonal to the first direction of the horizontal direction and having a length in an upper-lower direction shorter than that of the cell body portion. The battery case includes a frame member facing the cell terminal in the second direction. A stopper member is disposed in at least one of a space at an upper side of the cell terminal and a space at a lower side of the cell terminal and between the cell body portion and the frame member.
