摘要： A golf club head has a hollow structure comprising a main body member and a face member. The face member is made of an unidirectionally rolled plate of a titanium alloy having alpha phase crystals. The rolled direction of the unidirectionally rolled plate is inclined at an angle θ1 of not more than 30 degrees with respect to the horizontal direction. The face member is provided on the rear face with a ribbed part having its longitudinal direction inclined at an angle θ2 of not more than 30 degrees with respect to the vertical direction. A method for manufacturing the golf club head comprises a step of preparing the face member which comprises the steps of: preparing the unidirectionally rolled plate; cutting out a blank for the face member from the unidirectionally rolled plate; and forming the ribbed part on the cutout blank by machining.

Next, a reinforcing layer including a thermosetting resin composition is formed on the surface of this core to obtain a spherical body 40. Next, this spherical body 40 is covered by two pieces of half shell 46. Next, the spherical body 40 and the half shells 46 are placed into a mold 32. Next, the mold 32 is clamped at a velocity of 0.01 mm/sec or greater and 1.0 mm/sec or less. The thermoplastic resin composition of the half shell 46 is heated while being compressed in the spherical cavity to result in flow. This thermoplastic resin composition is hardened to give a cover having a thickness of 0.1 mm or greater and less than 0.7 mm. The difference (T−Fc) between the molding temperature T and the incipient fluidization temperature Fc of the thermoplastic resin composition of the cover is 0° C. or greater and 30° C. or less.
