| Zusammenfassung: | A golf club head includes a face portion, score lines n the face portion and extending in a toe-heel direction, protruding portions formed on the face portion and extending parallel to the score lines, and recessed portions formed on the face portion and extending parallel to the score lines. Each protruding portion and each recessed portion are formed alternately in a direction orthogonal to the toe-heel direction. The protruding portions include first protruding portions and second protruding portions. Each apex portion of the first protruding portions is positioned in a first imaginary plane parallel to a reference plane that contains each edge of the score lines. Each apex portion of the second protruding portions is positioned in a second imaginary plane parallel to the reference plane and different from the first imaginary plane. |
