<P>PROBLEM TO BE SOLVED: To provide a power storage device having excellent low-resistance and airtightness. <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; and an outer package 7 accommodating the element 1 with electrolyte. The power storage device further includes: a first frame 5 having a pair of connection parts 5a which are connected with the pair of leads 2c respectively; and a second frame 6 having a pair of connection parts 6a which are connected with the pair of leads 3c respectively. The lead parts 2c and 3c are connected with the first frame 5 and the second frame 6 so as to be exposed from the outer package 7. Therefore, because a component for a connection function is different from a component for a sealing function, the power storage device can reduce resistance and improve airtightness. <P>COPYRIGHT: (C)2012,JPO&INPIT |
