Zusammenfassung:	PROBLEM TO BE SOLVED: To inexpensively provide a golf club head improved in strength, especially fatigue strength while being made low in rigidity and improved in repulsion by using a titanium alloy having very low elasticity. SOLUTION: The golf club head is characterized in that a cold work in a working rate of ≥50% is applied to a Ti alloy containing Nb ≥12 wt.% and
