<p>PROBLEM TO BE SOLVED: To obtain an inexpensive golf club of which lie angle at a player's actual impact on a ball can be easily and precisely measured regardless of places. SOLUTION: A sole face 2 is shaped to form an arc-shaped section from the heel side of a head to the front end side and a plurality of marking lines 3 for lie angles are provided at a specified pitch on the sole face 2. A shaft is fixed to the head so that the axial line of the shaft and the ground face are positioned at a lie angle shown by a grounded marking line 3 for lie angles, when one of these marking lines 3 for lie angles is grounded.</p> |
