Abstract: A golf club head of the wood-type, including a body having a ball-striking face and a sole, is disclosed. The sole can include a wave slot for adding additional weight to the golf club head and for providing improved performance. The wave slot can include a front sidewall, a rear sidewall, and at least two waves. The waves can be positioned between the front and rear sidewalls and can each include a valley portion at the lowest point of the wave such that the valley portion does not protrude below the sole.

Abstract: A shoulder belt has a longitudinal direction and a transverse direction intersecting the longitudinal direction, and includes a first section and a second section spaced apart from each other in the transverse direction in a cross section intersecting the longitudinal direction, and a third section connecting between the first section and the second section. An expansion and contraction ratio of the third section is higher than each expansion and contraction ratio of the first section and the second section. Bending resistance of the third section is lower than each bending resistance of the first section and the second section.

The sole can include a wave slot for adding additional weight to the golf club head and for providing improved performance. The wave slot can include a front sidewall, a rear sidewall, and at least two waves. The wave slot can be open-ended. The waves can be positioned between the front and rear sidewalls and can each include a valley portion at the lowest point of the wave such that the valley portion does not protrude below the sole. The wave slot can also have two, three, or more waves, which can have heights that decrease as the position of the waves increases with respect to the ball-striking face.

Abstract: Provided are a golf club head and a golf club with a plate member that is resistant to peeling and has a glossy appearance. A golf club head includes a face portion including a ball striking surface, and a plate member connected to a back surface located on the back side of the face portion. The plate member includes a resin and a metal material. The metal material is arranged on at least any one of a toe side and a heel side of the face portion and is arranged so as not to planarly overlap a striking point of the face portion.
