Abstract: A golf club head comprising a face portion and a main body portion, wherein at least the face portion or a face of the face portion comprises an amorphous alloy having a glass transition range. The amorphous alloy preferably has a composition represented by the general formula X.sub.a M.sub.b Al.sub.c (where X is at least one element selected from the group consisting of Zr and Hf, M is at least one element selected from the group consisting of Mn, Fe, Co, Ni, Ti and Cu, and a, b and c are, in atomic percentages, 25.ltoreq.a.ltoreq.85, 5.ltoreq.b.ltoreq.70 and 0<c.ltoreq.35), and comprises at least 50% by volume thereof being an amorphous phase. The golf club head has a high strength and yet has a low elastic modulus.
