Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hollow golf club head which is improved in the finishing of its surface with decreased production stages, and further, has excellent strength. SOLUTION: This process for production consists in molding the central core of the golf club head by using wax, then installing the central core into a metal mold bored along with the external shape part of the golf club head. A kneaded mixture composed of metallic powder and a binder is then injected to the surface of the central core by a metal injection molding method using this metal mold, by which a green compact is molded. This green compact is then taken out of the metal mold and is vacuum dried. The green compact is then heated to elute the wax of the central core to obtain the hollow green compact. This green compact is sintered, by which the golf club head is produced.
