A golf club head of this invention includes a face and a plurality of striations formed on the face by milling. A pitch P in the arrangement direction of the plurality of striations satisfies 300 mum<=P<=600 mum. The surface roughness of a region in the face with the striations satisfies in the maximum height of the profile Ry, 15 mum<=Ry<=0.005xP+15.7 mum.
