It is characterized by attaching the constituent FRP molding material and inserting it into a mold and heat-pressing it. In this case, the weight member is fitted so that it is entirely buried in a recess formed on the surface of the core material. It is more preferable that a portion of the core material is temporarily held by protruding from the surface of the core material.

As shown in FIG. 1, numeral 1 in the figure is a head main body obtained by a manufacturing means described later. The head main body 1 is made up of an FRP outer shell 2 and a core material 3 made of foamed synthetic resin, and the core material 3 is made of lead, brass, etc. at appropriate locations corresponding to the head back surface 1a and sole surface 1b. A back weight member 4 and a sole weight member 5 made of metal materials are held in a partially protruding state, and the protruding portions 4a and 5a of each of the weight members 4 and 5 are embedded in the layer of the FRP outer shell 2. It has a fixed structure. In addition, in the figure, 6 is a face plate made of hardened FRP that is embedded and fixed in the FRP outer shell on the face surface portion 1c side of the head body 1, and 7 is a face plate that is inserted and fixed into the neck portion 1d of the head body 1. A cap-shaped protector 8 protects the club shaft 7 and the periphery of the attachment base between the club shaft 7 and the head body neck portion 1d.

すようなウツドクラブヘツドを得るものである。 That is, in order to manufacture the above-mentioned club head according to the present invention, as shown in FIGS. 2 to 4, a core made of foamed synthetic resin constituting the head core is prepared in advance using a desired mold (not shown). The head main body back surface portion 1a of the core material 11 is shaped.
Alternatively, if necessary, recesses 11a and 11b for fitting weight members may be formed at appropriate locations corresponding to the sole surface portion 1b, and portions 12a and 11b of the back weight member 12 and sole weight member 13 may be fitted into the fitting recesses 11a and 11b, respectively. Insert and hold with the protruding portion 13a (see Fig. 2). Next, the core material 11
Around the reinforcing fibers are impregnated with liquid powder hardened synthetic resin and semi-hardened as necessary.
The molding material 14 is rolled and coated (see FIG. 3),
By inserting and placing such a head molding material into the cavity 16 of the mold 15 having the outer circumferential shape of the head and hot-pressing it (see FIG. 4), a wood club head as shown in FIG. 1 is obtained. .
