PROBLEM TO BE SOLVED: To provide a secondary battery in which a collector terminal can be connected to the end of an electrode body without increasing the number of components and the man hours, and to provide the collector terminal structure of the secondary battery.SOLUTION: Restraint parts 20b, 20b bundling collector foils 20a are formed in an electrode body 20 at positions facing each other in the compressed direction. In each of two collector terminals 45, a collector part 45a of solid structure inserted between the restraint parts 20b, 20b and connected with the electrode body 20, and an electrification part 45b connected with the collector part 45a, formed with a width substantially equal to the thickness of the electrode body 20 in the compressed direction and arranged along both end faces in the winding central axis of the electrode body 20 are formed integrally. |
