<P>PROBLEM TO BE SOLVED: To provide a power storage device which is excellent in reduction of resistance. <P>SOLUTION: A power storage device has, at least: an element 1 which contains sheet positive electrodes 2 and negative electrodes 3 layered with a separator interposed therebetween and includes lead portions 2c, 3c for drawing electrodes formed at two opposite positions of each of the positive and negative electrodes 2 and 3, respectively; electrolyte impregnated in the element 1; a first frame 5 having a pair of connection portions 5a respectively connected to a pair of lead portions 3c; and a second frame 6 having a pair of connection portions 6a respectively connected to a pair of lead portions 2c. The electrodes are collectively drawn from the two positions of the element 1 by the first frame 5 and the second frame 6 so that the contact connection resistance between the element 1 and first frame 5 and between the element 1 and second frame 6 can be reduced. This can enhance output characteristics of the power storage device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
