Abstract
In a non-aqueous electrolyte secondary battery in which a battery element which is constructed by forming an anode active material layer and a cathode active material layer on an anode collecting body and a cathode collecting body, respectively, and laminating and winding them together with two separators, is housed in a battery can. An electrical connecting member for electrical connection between an inner electrode lead and an external terminal is designed to have spring property so that a winding core is pressurized and fixed to the center of the battery can, and the battery is structured such that connection between the inner lead and the connecting member can be made on an end face of the winding core inside of the battery can.
