PROBLEM TO BE SOLVED: To make a winding type electrode (an electromotive part) to realize high capacity with an excellent yield. SOLUTION: First of all, a belt-like positive electrode sheet 9, an inter-layer insulating sheet 10', a negative electrode sheet 8 and an inter-layer insulating sheet 10' are wound in a laminated spiral shape round a core body 7a. Next, an outer peripheral surface of a cylindrical electrode wound and formed round the core body 7a is pressed under almost constant pressure by rotary pressurizing rollers 13a and 13b by opposing in the diametrical direction. Here, the pressure of the pressurizing rollers 13a and 13b is reduced in an area where the positive electrode sheet 9 reaches a winding finish position after being wound and formed. |
