    • A golf club 2 includes a shaft 6, a tip member provided at a tip part of the shaft 6, and a rear end member attached to a rear end part of the shaft 6. The tip member includes a head 4. The rear end member includes a grip 8 and a weight member 20. The golf club has a club length of 1143 mm or more. A value of [W2/W1] is no less than 0.23 and no more than 0.32 when a weight of the tip member is W1 (g) and a weight of the rear end member is W2 (g). The weight member 20 is provided on a rear side relative to a tip position of the grip. The weight member 20 has a specific gravity larger than that of the shaft 6. The golf club 2 is a wood type golf club. Examples of materials for the weight member 20 include brass, a tungsten nickel alloy, an aluminum alloy, a tungsten alloy, a stainless alloy, stainless steel, and the like.

    • A real loft angle of a putter (2) is one to four degrees. In a reference section (D1), an intersection point of a line which passes through a center of gravity (g1) of a head and is perpendicular to a horizontal plane (H1) and a sole surface (18) is represented by (T1), a line passing through the point (T1) and a leading edge point (Le) is represented by (S1), a point which is present on the sole surface (18) and is provided apart from the line (S1) toward a lowermost side is represented by (T2), a line which passes through the point (T2) and is parallel with the line (S1) is represented by (S2), a distance between the point (T2) and the line (S1) is represented by (K1), a line passing through the point (T2) and the point (Le) is represented by (S3), a distance in the front-rear direction between the point (T2) and the point (Le) is represented by (L), and a distance in the front-rear direction between the point (T1) and the point (Le) is represented by (M). An angle (θ1) formed by the line (S3) and the horizontal plane (H1) is equal to or greater than two degrees and is equal to or smaller than ten degrees. (K1/M) is greater than zero and is equal to or smaller than 0.10. (L/P) is equal to or greater than 0.10 and is equal to or smaller than 0.50. A lower portion (22) positioned below the line (S1) is present between the point (T1) and the point (Le).
