Power storage device

A power storage device comprising:

• a plurality of laminated power storage modules;
• a flow path member disposed in contact with the power storage modules and having a plurality of flow paths configured to allow a cooling medium to flow along a first direction intersecting a laminating direction of the power storage modules;
• a pair of restraining plates disposed to sandwich the plurality of power storage modules and the flow path member in the laminating direction;
• a plurality of fastening members configured to apply a restraining load to the plurality of power storage modules and the flow path member via the pair of restraining plates by fastening the pair of restraining plates to each other;
• and
• a lead-in duct disposed at one end portion of the flow path member in the first direction and configured to lead the cooling medium into each of the plurality of flow paths, wherein
• the plurality of fastening members include a plurality of first fastening members arranged along an extending direction of the lead-in duct at one end portion of the restraining plate in the first direction, and
• each of the plurality of first fastening members extends along the laminating direction to pass through the inside of the lead-in duct.
