摘要： A golf club set 2 includes three or more golf clubs. A straight line passing through a face center Fc and parallel to a toe-heel direction is defined as an X-axis, and an X-coordinate of a sweet spot SS is defined as SS-X. When the SS-Xs of respective heads are defined as SS-X1, SS-X2, . . . , SS-Xn (n is an integer of equal to or greater than 3) in an ascending order of a loft angle from the head having the smallest loft angle, the set 2 satisfies the following formulas 1 and 2: SS-X1≥SS-X2≥ . . . ≥SS-Xn  (Formula 1); SS-X1>SS-Xn  (Formula 2).
