Golf club set

A golf club set constituted by a plurality of golf clubs having different loft angles,

• wherein each of the golf clubs includes a shaft and a golf club head,
• each of the golf club heads includes:
• a crown part;
• a face part;
• a sole part;
• and
• a hosel part to which the shaft is attached,
• in the face part, a lower edge line that is a boundary with the sole part curves so as to protrude downward,
• when a first point, a fourth point, and a fifth point are defined on the lower edge line, the first point being the lowermost point when the golf club head is in a reference state, the fourth point being an intersection point of the lower edge line and a plane that passes through an intersection point of a center axis line of the shaft in the reference state and a placement surface and that is perpendicular to a toe-heel direction, and the fifth point being a midpoint between the first point and the fourth point, the lower edge line includes a first heel-side lower edge line that extends from the fourth point to the fifth point, and a second heel-side lower edge line that extends from the first point to the fifth point, and
• out of the plurality of golf clubs, at least a pair of a first golf club having a lower loft angle and a second golf club having a higher loft angle are configured such that a curvature radius of the first heel-side lower edge line of the second golf club is smaller than a curvature radius of the first heel-side lower edge line of the first golf club.
