<P>PROBLEM TO BE SOLVED: To provide a power storage device having excellent low-resistance. <P>SOLUTION: A power storage device at least includes: an element 1 in which sheet-like cathodes 2 and sheet-like anodes 3 are laminated with separators interposed between them and which comprises lead parts 2c and 3c provided at two opposite parts of the cathode 2 and the anode 3, respectively, and each drawing out an electrode; electrolyte impregnated within the element 1; and a first frame 5 and a second frame 8 respectively having a pair of connection parts 5a and 8a which are connected with the pair of leads 2c and 3c respectively. The first frame 5 and the second frame 8 are insulated from each other. The inside surface of the first frame 5 is opposed to the element 1 and a part of the inside surface of the second frame 8 is opposed to the outside surface of the first frame 5. The first frame 5 has a protrusion part at a position opposed to the second frame 8, and the second frame 8 has an open hole, at a position opposed to the first frame 5, in the opposed direction so that the protrusion part is exposed on the outside surface of the second frame 8 through the open hole. <P>COPYRIGHT: (C)2012,JPO&INPIT |
