Abstract: Provided is a golf club head having a sole portion. In the sole portion, first and second grooves are formed extending in a toe-heel direction and recessed toward the inside of the sole portion. The first groove is disposed on a face side relative to the second groove. The first groove includes a first main inner wall and a first sub inner wall shorter than the first main inner wall. The second groove includes a second main inner wall and a second sub inner wall shorter than the second main inner wall. The first and second main inner walls are inclined so as to point upward toward the face side. The second main inner wall, when the sole portion has been placed on a ground plane, is inclined more steeply than the first main inner wall relative to the ground plane in a side cross-sectional view.
