1. A golf club, comprising:
- a golf club head including a head body and a pair of balance adjustment portions formed in the head body;
a plurality of weights detachably retained in each balance adjustment portion of the pair of balance adjustment portions so that a three-dimensional gravity center position of the golf club head is adjusted, the plurality of weights serving as balancers and differing from each other in density and mass; and
an Integrated Circuit (IC) chip accommodating portion that is formed in the head body or one of the balance adjustment portions to house an IC chip that stores information on the three-dimensional gravity center position of the golf club head, wherein each balance adjustment portion includes a clubface side balance adjustment portion having a clubface recess formed in a clubface side of the head body, a clubface plate covering the clubface recess, an inner plate made of a metal having a higher thermal conductivity than the head body and the clubface plate, located between the clubface plate and the clubface recess and detachably bonded to the clubface plate and the head body, a communication hole formed in a backface side of the head body and communicating with the clubface recess, and a cover plate detachably covering a backface side of the communication hole; and
the third-dimensional gravity center position information stored on the IC chip includes at least one of materials, densities and mass of the clubface plate, the inner plate and the cover plate.
