Zusammenfassung:	PROBLEM TO BE SOLVED: To increase the degree of freedom of head rigidity design, mass distribution, centroid position design by it and inertia moment design by reducing weight and increasing a weight margin at the time of design in a hollow golf club head. SOLUTION: The hollow golf club head is constituted by joining a top member and a sole member composed of a resin such as CFRP, GFRP or FRTP to the opening parts of a head main body made of a metal such as stainless steel, a titanium alloy or an aluminum alloy in which the large parts of a top part and a sole part are respectively opened.
