<P>PROBLEM TO BE SOLVED: To properly cool a die by application of a die release agent so as to improve die releasability. Ž<P>SOLUTION: When a lower die 1 and an upper die 3 are opened after forge forming, a spraying header 5 for a die release agent is set between the dies 1 and 3, and the die release agent is sprayed from each of nozzles 9a-9e and 11a-11e of the header 5 to each of portions 1a-1e of the lower die 1 and portions 3a-3e of the upper die 3, which face to the nozzles 9a-9e and 11a-11e respectively. At this time, a die release agent R2 that has medium viscosity is applied to high-temperature portions 1a, 1e, 3a, 3e of a forging face, and a die release agent R3 that has low viscosity is applied to low-temperature portions 1b, 1d, 3b, 3d of the forging face.
