In the club head 5 on the long iron side, a core 7 such as FRP is placed on a metal head 6. The outer periphery is covered with an outer shell 8 made of fiber reinforced plastic or the like to be integrally formed.

FIGS. 4 to 6 show a front view and a sectional view of a club head 9 of a club S on the short iron side, and a sectional view showing another embodiment. The short iron club S is formed from a metal head. A plate member 12 made of a non-metallic material such as fiber reinforced plastic as shown in FIG. 5 is attached to the hitting portion 11 of the club head main body 10 or the hitting of the club head main body 10 as shown in FIG. Part 11
In this embodiment, a hitting member 14 made of a nonmetallic material such as fiber reinforced plastic is inserted into a hollow portion 13 formed as described above.

That is, the club head 9 of the short iron club S is formed by
Only, using a non-metallic material such as fiber reinforced plastic, and with such a configuration, both functions of the middle iron club and the short iron club S, both of the hitting distance and the control of the hitting ball Is provided. More specifically, by providing the club head main body portion 10 made of a metal head on the sole side and the back side of the club head, a low center of gravity design of the club head is facilitated, and as a result, the ball is easily lifted, and the ball is hit easily. By using a non-metallic material having a large coefficient of restitution for the portion 11, the flight distance of the ball can be extended.

In the present invention, as described above, the golf club is designed so that each of the clubs L on the long iron side and the club S on the short iron side can fully perform their functions.
