ABSTRACT:
A golf club head has a face portion, a crown portion, a sole portion, a side portion and a hosel portion. Each portion is made of titanium or a titanium alloy. The side portion is formed integrally entirely from its toe side to its back side and its heel side. The side portion and the hosel portion are cast integrally. The face portion, the crown portion and the sole portion are molded separately from one another. The face portion, the crown portion, the sole portion and the side portion are welded integrally so as to form a golf club head. The Young's modulus of the crown portion is lower than any Young's modulus of the face portion, the sole portion, the side portion and the hosel portion.
