PROBLEM TO BE SOLVED: To efficiently adjust a temperature of a power storage element using a heat exchanging medium.SOLUTION: A power storage device has plural power storage elements 10A, 10B, 10C, and a bus bar electrically connecting the plural power storage elements. Each power storage element extends in a predetermined direction, and has a positive electrode terminal and a negative electrode terminal on both ends in a predetermined direction. The plural power storage elements are aligned in a plane orthogonal to the predetermined direction. The bus bar has: a positive electrode connection section connected to the positive electrode terminal of the power storage element; a negative electrode connection section connected to the negative terminal of the power storage element; and intermediate connection sections 22, 32 extending in the predetermined direction and respectively connected to the positive electrode connection section and the negative electrode connection section on both ends. The intermediate connection sections are arranged on at least some of the power storage elements on a discharge side of a moving path of a heat exchanging medium used for adjusting a temperature of the power storage element. |
