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.
