1. A golf club comprising:
- a golf club head having a face on a front and formed by an outer shell member so as to be hollow;
a shaft having a bottom end connected to a neck formed on one side of said golf club head; and
a grip provided on an upper portion of said shaft,wherein said outer shell member comprises;
an edge frame made from metal; and
a shell body made from resin and provided inwardly relative to said edge frame, said shell body enveloping and entirely covering both front and rear surfaces of an inner edge of said edge frame with the same thickness by a casting manner, whereinsaid edge frame comprising a metal has an inner edge, wherein a front surface a rear surface of the edge frame adjacent to said inner edge form a concave portion such that the inner said becomes thinner;
said edge frame made from metal has a plurality of reinforced ribs provided in a reticular pattern, wherein said plurality of reinforced ribs have a front surface and a rear surface that form a concave portion near an edge of said reinforced ribs such that the edge of said reinforced ribs becomes thinner; and
said shell body made from resin envelops said plurality of reinforced ribs by a casting manner.

Abstract
The partial crown portion member comprises: the edge frame made from metal; and the shell body provided inside the edge frame and made from resin enveloping the inner edge of the edge frame. Inside the edge frame, the plural through-holes penetrating the front surface of the edge frame to the rear surface thereof are provided, while the shell body is inserted in the through-holes by casting manner. Since the front and rear surfaces of the inner edge of the edge frame, the through-holes are enveloped by casting manner, the adhesiveness thereof can be enhanced.
