<P>PROBLEM TO BE SOLVED: To provide a wound power storage element capable of preventing the generating element from oscillating. <P>SOLUTION: The wound power storage element comprises a flat generating element including a winding core and a positive electrode plate and a negative electrode plate wound around the winding core, a case housing the generating element, an output terminal placed on the outer surface of the case, and a collector which connects the generating element and the output terminal electrically. The winding core includes a pair of arcuate parts composed at least of a double resin sheet arranged in mirror image while spaced apart in one direction in a state where the inner peripheral surfaces are facing each other, and a pair of counter parts where the one ends and the other ends of the pair of arcuate parts facing each other are interconnected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
