A club-head for a golf club includes a hitting portion (11) having a front surface (11a) for hitting a golf ball, a rear surface (11b), a sole surface (11c) and heel and toe ends (11d, 11e), and a hosel portion (12) extending obliquely upward from the heel end (11d) of the hitting portion. The hitting portion (11) comprises a main body (13) made of a fiber-reinforced plastic for defining at least a part of the front and rear surfaces (11a, 11b) of the hitting portion. A metal sole member (14) having a specific gravity greater than that of the main body (13) is integrally joined to the main body (13) along the underside of the main body for defining at least the sole surface (11c) of the hitting portion (11). A reinforcing plate (19) is fitted at the lower end portion thereof into the sole member (14) and extends upwardly from the sole member into the main body (13) substantially in parallel to the front surface (11a) of the hitting portion (11). The reinforcing plate (19) has a specific gravity less than that of the sole member (14) and a strength greater than that of the main body (13).
