摘要： The present invention provides a golf club improved in ball hitting sound and ball hitting feeling and its manufacturing method. First, low-carbon steel is subjected to press processing of hot forging to form portions of irregularity on the face on a side of a hitting surface. Then, when there are projecting portions in the portions of irregularity, only the projecting portions are subjected to press processing of cold forging to crush the projecting portions to be flat. Then, the surface is slightly smoothed by machining to be flat and crystal grains at the portions of irregularity and the area therearound are pressed to be fined, thereby enhancing the hardness and forming fiber flows parallel to the hitting surface. A part of the hardened face becomes harder than the hardness of a base material before press processing by 10% or more within a range of 1 mm in a depth.

摘要： A golf club having an increased moment of inertia and improved ball-hitting directionality is provided. A metal hollow golf club head comprises: a face portion; a crown portion; and a sole portion, and when the golf club has a lie angle of 60° with its club head volume being within 470 cm3, a moment of inertia about the axial line centered on the plumb line passing through the golf club head center of gravity is 5000 to 6000 g-cm2. In order to increase the moment of inertia, the thickness of the center portion of the crown portion is reduced by chemical etching, and a mass, including the portion of mass reduction, is positioned in the sole portion on the side of the toe portion; moreover, the separation distance from the center of gravity to the mass is increased.
