PROBLEM TO BE SOLVED: To easily form many pins for machining at high precision regarding a tool for piercing used for an ultrasonic machine. SOLUTION: A resist film 22 is formed on the face of a base metal 21. Light for removing each resist film 22 is emitted corresponding to each position of the face of the base metal 21 at which pins 23 for working are formed, and each resist film 22 is removed till the face of the base metal 21 appears. The plating films (pins for working) 23 by electroforming plating are formed at the parts freed from the resist films 22 in the face of the base metal 21, and, thereafter, each resist film 22 remaining on the face of the base metal 21 is removed.
