While swinging the electrolytic etching liquid, a current is supplied from the power source 9 between the metal workpiece 1, which is an anode, and the cathode 5 through the electrolytic etching liquid, thereby forming the metal workpiece 1. Electrolytic etching can be achieved through the openings 3 of the mold pattern 2 according to the shape and size of the openings 3, and after the electrolytic etching is completed, the mold pattern is removed and the next electrolytic etching is performed. By placing the die pattern in close contact with the metal workpiece to be processed and performing electrolytic etching in the same manner, it is possible to perform electrolytic etching on a large number of metal workpieces by sequentially using only one die pattern that is electrolytically etched in the same manner. The electrolytic etching liquid is sprayed uniformly over the entire surface of the metal workpiece, making the current density uniform between the cathode and the anode. A uniform electrolytic etching is obtained, and therefore an extremely high degree of precision can be obtained.
