<p>PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode in which an electrode material can be punched in a state where the positional deviation in the width direction is suppressed, and also to provide an electrode material.SOLUTION: In a method of manufacturing a positive electrode, a press die 50 for performing a punching step includes a blade part 52 along the outer shape of the positive electrode. Then, in the punching step, by inserting positioning projections 53 attached to an upper die 51 of the press die 50 into positioning holes 22a provided on both sides in the width direction of an electrode material 30, the electrode material 30 is punched by the blade part 52 in a state where the electrode material 30 is extended in the width direction.</p> |
