<P>PROBLEM TO BE SOLVED: To provide a forging method of a metal capable of reducing deformation resistance of a metal material by applying ultrasonic vibration to a machining tool and a die for forging and carrying out molding with less pressurizing force, and also provide a forging device of the metal. Ž<P>SOLUTION: The forging device has a moving tool and a fixing tool which are for plastically processing a workpiece by clamping it and is provided with an ultrasonic resonator mounted at a moving tool side and oscillating ultrasonic vibration, a main body frame for holding these, and a mechanism for pushing out the frame itself. In the forging method of the metal, vibration is applied in the same direction as that of forging to the die. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
