PROBLEM TO BE SOLVED: To improve in reliability of a storage element by surely restraining generation of inner short circuiting, liquid leak, or the like while enabling to increase storage energy density and chargeable and dischargeable current, through increase of the number of lamination of electrode sheets and gathering of current collecting lead parts of the electrode sheets for common connection with outer terminal leads, in a manufacturing method of the storage element using a flat multilayer electrode body made by alternately laminating a flat cathode sheet and an anode sheet through a separator. SOLUTION: The manufacturing method includes a molding process molding so as to gather current collecting lead parts 212, 233 extended sideways of the electrode body 20 at a given position in its thickness direction while retaining a laminated form of the same 20, and a welding process connecting by welding the current collecting lead parts gathered by the above process to outer terminal leads 31, 33 of the cathode and the anode at a given position in a thickness direction of the above electrode body.
