    • A golf club head of this invention includes a face, a plurality of score line grooves formed on the face, and traces formed in the face by milling. Edges of the score line grooves are rounded with a radius of not more than 0.2 mm. A width W (mm) of the score line groove measured with the rounded edge being included, a width Ws (mm) between the score line grooves adjacent to one another, a width Wr (mm) of the score line groove measured based on the 30 degrees measurement rule and a cross section area S (mm2) of the score line grooves satisfy the flowing expressions; W/Ws×100≧35(%) and S/(Wr×0.5)×100≧70(%). The face in which the traces are formed has the arithmetic mean deviation of the profile (Ra) of not less than 4.00 μm.
    • 本发明的高尔夫球杆头包括面,形成在面上的多个刻痕线槽,以及通过研磨形成在表面上的迹线。 刻痕线槽的边缘以不大于0.2mm的半径圆化。 包括用圆形边缘测量的刻痕线槽的宽度W(mm),彼此相邻的刻痕线槽之间的宽度Ws(mm),基于 刻度线槽的30度测量规则和横截面面积S(mm <2)满足流动表达式; W / Ws×100> = 35(%)和S /(Wrx0.5)×100> = 70(%)。 痕迹形成的面具有不小于4.00μm的轮廓(Ra)的算术平均偏差。

    • A hollow golf club head according to this invention includes a face portion, a crown portion, and a sole portion, and is formed by connecting a plurality of shell members to each other. This golf club head includes a rib which is provided in the sole portion and used to adjust an impact sound. The plurality of shell members are divided using at least the rib as a boundary. The plurality of shell members include a rib forming shell member including a sole portion forming portion which forms part of the sole portion, and a rib forming portion which stands upright from the end of the sole portion forming portion and forms the rib.
    • 根据本发明的中空高尔夫球杆头包括面部,冠部和鞋底部分,并且通过将多个壳体构件彼此连接而形成。 该高尔夫球杆头包括设置在鞋底部分中并用于调节冲击声的肋。 使用至少肋作为边界来分割多个壳体构件。 多个外壳构件包括形成肋构件的肋构件,其包括构成鞋底部分的一部分的底部部分形成部分和从底部形成部分的端部竖立并形成肋的肋形成部分。
