PROBLEM TO BE SOLVED: To provide a power storage device in which the stress working on a coil conductor is small, and which has a highly stable coil and is high in reliability and small in installation area. SOLUTION: A power storage device, which generates a magnetic field by applying currents to the coil 1 made by winding a superconductor, and stores energy, has one or more places of straight parts at the winding part of the coil 1. This power storage device has a support structure 10 in the form of connecting the two or more places of straight parts, and also has a support structure 12 to directly couple a building, wherein the power storage device is installed, with a coil. |
