Abstract: A golf club 2 includes a shaft 6 having a weight of 50 g or less. The shaft 6 has a ratio of a center of gravity of 0.54 or greater. Respective EI values measured at intervals of 100 mm from a point 130 mm distant from a tip end Tp are defined as E1 to E10. A first region, a second region, and a third region are defined by boundaries at respective points having distances of 230 mm and 830 mm from the tip end Tp. In a graph on which the EI values are plotted, gradients of approximate straight lines in the first region, the second region, and the third region are defined as M1, M2, and M3, respectively. M1 to M3, E9/E6, and E10/E6 are fall within respective specified scopes. M3 is greater than M2.
