Claim:
A golf club head comprising: a face line having a depth of D 1 (mm); and a land area, wherein when a boundary between the land area and the face line is defined as a point Pa in a section line of a surface of a face; a point of which a depth is [D 1 /4] (mm) is defined as a point Pb; a point of which a depth is [D 1 /2] (mm) is defined as a point Pc; a point of which a depth is [(D 1 )×(¾)] (mm) is defined as a point Pd; a point of which a depth is 0.002 (mm) is defined as a point Px; a radius of a circle CL 1 passing through three points of the point Pa, the point Pb, and the point Pc is defined as R 3 (mm); a straight line passing through the point Pa and the point Px is defined as a straight line Lax; and an angle between the land area and the straight line Lax is defined as θ 2 (degree), the radius R 3 is 0.2 (mm) or greater and 0.4 (mm) or less, and the angle θ 2 is 10 degrees or greater and 50 degrees or less.
