Abstract
A method for manufacturing a golf club head, which enables a face to be formed thinner to realize a more free distribution of weight. A flat surface 1A of a head body 1 is formed with plural cavities 6 to strengthen a face 4. Thus, the face 4 can be made thinner, which enables the distributing of thus obtained surplus weight to other parts of the head body 1. Each cavity 6 is disposed opposite to an area 9A between adjacent score lines 5. Accordingly, sufficient thicknes A of the face 4 can be guaranteed to prevent the degradating of strength caused by forming the thinner face 4.
