Disclosed are a punching metal manufacturing method and device using manufacturing technology efficient in manufacturing punching metal, and capable of forming with high precision through-holes of diameter 100-500µm in a 1-100µm thick foil of copper, aluminum or other metal or metal alloy, with a prescribed hole ratio, and with few burrs. In the disclosed punching metal manufacturing method, a male mold (1) having a punch (5) and a female mold (2) having a die (6) are brought together and separated by the reciprocating motion of a punching drive mechanism so as to repeatedly perform pressing and releasing to punch with a predetermined pattern to form through-holes (8) in a metal foil (4) held between the male and the female molds, wherein ultrasonic vibration is applied to the female mold and punching is performed while the ultrasonic vibration acts on the metal foil during pressing. |
