A golf club head 2 comprises: a porous part Ps including a porous metal and integrally formed; and a non-porous part NPs. The porous part Ps constitutes at least a part of a sole 8. The porous part Ps has a whole thickness part Pt occupying a whole thickness of the sole 8. Preferably, a rate Ra of an area occupied by the whole thickness part Pt among an area of the sole is equal to or greater than 15%. Preferably, the porous part Ps and the non-porous part NPs are welded mutually. In the disposal of the porous part Ps in the head 2, preferably, a substituted head obtained by substituting the porous part Ps with the same material as that of the non-porous part NPs adjacent to the porous part Ps is considered.
