<p>PROBLEM TO BE SOLVED: To provide a golf club head capable of increasing the flying distance of a golf ball by increasing a ball hitting angle and decreasing backspin quantity when the golf ball is hit. SOLUTION: In the golf club head, the frequency indicating the linear minimum value of the mechanical impedance of the club head is from 600 Hz to 1,400 Hz when the position of an intersection point of a face and the perpendicular line dropped from the centroid of a single club head to the face is vibrated by an exciter, and the coefficient of friction of the face is 0.35 to 0.60.</p> |
