<P>PROBLEM TO BE SOLVED: To provide a power storage element including a collector member that prevents increase of a resistance value. <P>SOLUTION: A battery 10 of the present invention includes: a power generation element 11 formed by winding or laminating a positive electrode plate 12 and a negative electrode plate 13 through a separator; a case 20 housing the power generation element 11 and including a terminal 25 for external connection; and a collector member 40 having a pair of electrode plate connection parts 43 electrically connected to either electrode plate 12 or 13 of the positive electrode plate 12 and the negative electrode plate 13. In the collector member 40, at least one of the pair of electrode plate connection parts 43 is continued to a terminal connection part 41 connected to the terminal 25, the pair of the electrode plate connection parts 43 are formed long and disposed so as to face each other, and respective long sides of the pair of electrode plate connection parts 43 are mutually connected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
