NOVELTY - A secondary battery has an electrolyte resistant metal presser(s) (10) which is arranged between current collecting portion of positive electrode and cover body (8) separately from a metal lead plate (5). The current collecting portion of the positive electrode and the cover body are electrically connected by the metal presser separately from the metal lead plate, and an electrode group (E) is in a state of applied pressure by the cover body and a bottom portion (4a) of a bottomed cylindrical can (4).    USE - Secondary battery for hybrid electric vehicles and electric vehicles.    ADVANTAGE - The secondary battery has improved internal impedance, and high-rate discharge.    DETAILED DESCRIPTION - A secondary battery comprises an electrode group (E) in which a positive electrode and a negative electrode are spirally-rolled interposing a separator in between them contained in a bottomed cylindrical can (4), sealed by a cover body (8), and a metal exposure portion provided on an end surface of the positive electrode of the electrode group or a metal-made current collecting plate electrically connected to the metal exposure portion (or current collecting portion of the positive electrode) and the cover body also functioning as a positive electrode terminal being electrically connected by a metal lead plate (5). Electrolyte resistant metal presser(s) (10) is arranged between the current collecting portion of the positive electrode and the cover body separately from the metal lead plate. The current collecting portion of the positive electrode and the cover body are electrically connected by the metal presser separately from the metal lead plate, and the electrode group is in a state of applied pressure by the cover body and the bottom portion of the bottomed cylindrical can.
