Abstract

A battery pack () in which a cell stack () having a plurality of rectangular cells () stacked is housed in an interior of a battery case () includes an end plate () disposed on one end side in a stacking direction of the cell stack (), a wedge member () disposed on the side of the end plate () opposite to the cell stack (), and a bolt () disposed in a bolt screw-in direction that is orthogonal to the stacking direction and urging the wedge member () toward a bottom wall () of the battery case (), and first abutment faces () via which the wedge member () and the end plate () abut against each other are formed from an inclined face that is inclined toward the bolt () side in the bolt screw-in direction. Therefore, it is possible to apply strong compression to the cell stack () with a simple structure and to suppress expansion of the rectangular cell (), and moreover to enhance the energy density per unit volume while reducing the dimensions and weight of the battery pack ().
