PROBLEM TO BE SOLVED: To provide a power storage device in which a useless space is prevented from being formed between modules when a plurality of modules are arranged.SOLUTION: The power storage device includes a first cooling substrate 10 arranged in contact with one side of a first module A, and a second cooling substrate arranged in contact with one side of a second module B. The first and second cooling substrates 10, 20 are arranged side by side along the same plane. The first and second cooling substrates 10, 20 have connections 11, 12, 21, 22, respectively. When the first and second modules A, B are arranged side by side, the connections 11, 12, 21, 22 are formed at different positions in a direction orthogonal to the arrangement direction. |
