Zusammenfassung:	PROBLEM TO BE SOLVED: To manufacture a golf club head made of titanium which is excellent in the mechanical characteristics such as strength, durability, etc., and emits a mild ball striking sound like persimmon wood where the reverberation of the ball striking sound in the frequency band 4-10kHz remains low and a mettalic tone is suppressed. SOLUTION: In manufacturing a golf club head made of titanium, an α+β type titanium alloy is subjected to a processing at a temp. in the range from more than the β-transformation temp. minus 100 deg.C to less than the β-transformation temp., followed by a heat treatment within temp. range more than 750 deg.C to less than 1100 deg.C, and the obtained substance is used at least in the face part 1, and thereby the reverberation of a ball striking sound in the frequency band 4-10kHz is lowered.
