<p>To provide a golf club head which is easy-to-hit and which restrains the reduction of flight distance at the time of off-center shot to the minimum without making a sacrifice of the flight distance at the time of sweet spot shot, and a method for manufacturing the golf club head, a golf club head (1) has a hollow structure including a face portion (2) and a body portion (6), the body portion (6) includes a ring-shaped body barrel portion (26) as a front portion, and a tail portion (27) as a rear portion, and the average thickness of the body barrel portion (26) is 0.1 to 0.6 mm, and the mass of the tail portion (27) including a weight portion (8) is 20 to 70 g. The relations kb/kf≰3 and 2 kN/mm≰1/(1/kb+1/kf)≰5 kN/mm are satisfied where kf (kN/mm) is the rigidity of the face portion (2) and kb (kN/mm) is the rigidity of the body barrel portion (26).</p> |
