A sole portion of a golf club head includes a first portion contacting with ground
in address position and a second portion being raised in a direction from the first
portion toward a toe portion. The first and second portions are each in a shape
of a curved surface convex toward the outside of a head body. An angle of the second
portion with respect to the first portion is adjusted such that an angle formed
by a first plane contacting with a vertex of the first portion in address position
with a prescribed lie angle and a second plane contacting with a vertex of the
second portion becomes at least 30 and at most 60.
