    Abstract: The golf club head of the present invention includes a face portion, a crown portion, and a sole portion. The golf club head also has an interior space surrounded by the face portion, the crown portion, and the sole portion. A first channel and a second channel that extend in a toe-heel direction and are recessed toward the interior space side are formed in the sole portion. The first channel is disposed on a face side relative to the second channel, and has a first main inner wall disposed on the face side, and a first sub inner wall disposed on a back side. The first main inner wall is formed with a longer length in a face-back direction than the first sub inner wall, and is inclined so as to extend upward while extending toward the back side.

    Abstract: A set 2 includes two or more iron type golf clubs 4 having loft angles different from each other. Each club 4 includes a shaft sf, a head hd, and a grip gp. The head hd includes a top surface 10, a sole surface 12, and a face surface 14 having a face line gv. The sole surface 12 includes a leading edge E1 and a trailing edge E2. In a planar view of the sole surface 12, the trailing edge E2 is curved so as to project toward a face side. A sole width WSc at a middle position of the face line gv is increased as the loft angle is increased.
