<P>PROBLEM TO BE SOLVED: To suppress deterioration in a function of a separator when a collector member and tab groups of electrodes are connected. <P>SOLUTION: A secondary battery includes: a plurality of positive electrode tab groups 24 formed on an electrode body 23; a collector terminal 17 which includes a plurality of joint parts 35 and 36 facing each other and a base part 33, and in which at least one of the positive electrode tab groups 24 is connected to each of the joint parts 35 and 36 formed of conductive materials; and a connecting member 37 for connecting the positive electrode tab groups 24 with each of the joint parts 35 and 36. The connecting member 37 includes: a support part 37a which is interposed between each of the joint parts 35 and 36; shaft parts 38 and 39 which are extended from both ends of the support part 37a in a front and back direction along the front and back direction and are inserted in notch parts 35a and 36a of each of the joint parts 35 and 36; and head parts 38a and 39a which are provided at the tip of the shaft parts, and connect the positive electrode tab groups 24 with the joint parts 35 and 36 by sandwiching the positive electrode tab groups 24 with the joint parts 35 and 36. <P>COPYRIGHT: (C)2013,JPO&INPIT |
