In A golf club head, a central portion of a sole surface existing substantially centrally between the toe and heel sides is left as it is, two recesses are formed on the toe and heel sides, and the wall surfaces of the recesses are formed so as to be inclined gently from the sole surface central portion. The golf club head can cut into the ground properly when hitting a ball and also allows a golfer to hook or slice the ball freely.
