Golf club
A golf club includes a head; a shaft; a grip; and a weight member that is located in a butt end region. The grip and the weight member constitute a grip-weight portion. The shaft, the grip, and the weight member constitute a shaft-grip-weight portion. The golf club has a length of greater than or equal to 45.0 inches. The golf club has a weight of less than 295 g. The head has a weight of greater than or equal to 195 g. The grip-weight portion has a weight of greater than or equal to 40 g. W 1 /W 3 is greater than or equal to 0.40, where W 1 represents a weight (g) of the butt end region, and W 3 represents a weight (g) of the shaft-grip-weight portion.
