An object of the invention is to improve a directionality of a hit ball. The invention provides a golf club head ( 1 ) having a face portion ( 3 ), a crown portion ( 4 ), a sole portion ( 5 ) and a side portion ( 6 ). The golf club head includes a head base body (M) made of a metal material and provided with at least one opening portion (O), and a cover body (FR) arranged in the opening portion (O) and made of a lower specific gravity material having a specific gravity smaller than the metal material. In a head toe side portion ( 1 t) and a head heel side portion ( 1 h) virtually sectioned by a vertical surface (VP) including a normal line (N) drawn from a head gravity point (G) to a face surface ( 2 ) in a standard state, a surface area (St) of the cover body (FR) covering the opening portion (O) included in the head toe side portion ( 1 t) is made larger than a surface area (Sh) of the cover body (FR) covering the opening portion included in the head heel side portion ( 1 h), and a weight (Wh) of the head heel side portion ( 1 h) is set to 55 to 75% of the entire weight (W) of the head.
