PROBLEM TO BE SOLVED: To provide a power storage device that can suppress a decrease in energy efficiency, can improve reliability, and can be made compact. SOLUTION: The power storage device 1 includes a power storage device body 2, and an exterior film 3 which contains the power storage device body 2 in a state where the power storage device body 2 is dipped in an electrolyte. The power storage device body 2 has first and second electrode sheets 4 and 5, and a separator 6 held between the first and second electrode sheets 4 and 5. The first electrode sheet 4 has: a first current collecting foil 7; and a first electrode 8 provided to the first current collecting foil 7 while avoiding a first current collecting foil-exposed part 7a as a portion of the first current collecting foil 7. The second electrode sheet 5 has: a second current collecting foil 9; and a second electrode 10 provided to the second current collecting foil 9 while avoiding a second current collecting foil-exposed part 9a as a portion of the second current collecting foil 9. The first and second current collecting foil exposed parts 7a and 9a are exposed as terminals to the outside of the exterior film 3. COPYRIGHT: (C)2011,JPO&INPIT |
