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.
