PROBLEM TO BE SOLVED: To provide a rectangular battery that has high volumetric efficiency and a high sealing property. SOLUTION: In a rectangular battery that encloses a generating element formed by winding a band-shaped positive and negative electrodes interposing a separator between them in a prismatic battery can 1 and is sealed with an electrode header 5, the electrode header 5 is structured by forming a through- hole for a conductive connection terminal 4 on a recessed part 3A, formed on the upper surface of a metal plate 3 and installing insulating plates on the upper and lower surfaces of the recessed part 3A, so as to insulated the metal plate 3 from the conductive connection terminal 4 and to fix the conductive connection terminal 4 and the metal plate 3 by means of crimping the conductive connection terminal 4. The conductive connection terminal 4 is consecutively connected with one of the electrode plates of the generating element. The electrode header 5 is fixed on the battery can 1 at the position, where the upper surface of the electrode header 5 so as to be flush with the upper edge of the battery can 1. |
