Abstract: Provided is a golf club having a head disposed at a front end of a shaft and a grip disposed at a back end of the shaft. A club weight is not larger than 290 g, and a ratio (head weight/club weight) of a head weight to a club weight is not lower than 0.67 but not higher than 0.72. When an inertia moment of the club at a grip end is MI, 2700 kg·cm2≦MI≦3000 kg·cm2 is satisfied, and when a frequency of flexural vibration of the club is F, 190 cpm≦F≦230 cpm is satisfied.

Abstract translation: 提供一种高尔夫球杆，其具有设置在轴的前端的头部和设置在轴的后端的把手。 俱乐部重量不大于290g，头重与球杆重量之比（头重/球杆重量）不低于0.67但不高于0.72。 当握柄端的球杆的惯性力矩为MI时，满足2700kg·cm2 @ MI @ 3000kg·cm2的情况，并且当球杆的弯曲振动频率为F时，满足190cpm @ F @ 230cpm 。
