PROBLEM TO BE SOLVED: To suppress temperature variation among power storage elements which are stacked and arranged.SOLUTION: A temperature adjustment structure of a power storage device according to the present invention comprises: a pair of end plates sandwiching a plurality of power storage elements in a stacking direction, and a spacer that is alternately stacked in the power storage element, and forms a space for passing through a cooling air. A flow inlet and a flow outlet of the cooling air to the space are formed in the spacer, respectively. In the spacers, a first spacer arranged between the power storage element adjacent to the end plate in at least predetermined direction and the end plate includes a guiding part that is extended to an opening inner side so as to prevent from blocking an opening in one of at least the flow inlet and the flow outlet.SELECTED DRAWING: Figure 1 |
