Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a forging method by hot forging by which a degree of freedom of a design shape is increased as compared with a conventional method, and a forged product preventing problems of mechanical strength degradation, stress corrosion cracks or the like can be manufactured inexpensively.SOLUTION: Forging by hot forging is carried out by a hot forging device 11 including: a forging device in which two or more process units 13 are detachably incorporated in a same forging machine; a plurality of heaters for heating molds in the respective process units 13; a plurality of thermocouples for detecting temperatures of the molds of the respective process units 13; a non-contact type thermometer for detecting a temperature of the forged product; and a mold temperature control device for controlling the plurality of heaters based on outputs of the non-contact type thermometer and the plurality of thermocouples.
