A reference state is envisioned in which a golf club is placed on a
horizontal plane P with a predetermined lie angle and face angle, and the
shaft axis line thereof is disposed within a reference plane that is
perpendicular to the horizontal plane P. A center of gravity of the head
G is positioned on the back side of the head from the reference plane,
and a depth of the center of gravity D that is a distance between the
reference plane and the center of gravity of the head G is 20 mm or
greater and 30 mm or less. The golf club has a flexural rigidity value
EIt (kgfmm.sup.2) of the shaft at a position T3 140 mm away from the tip
on the head side being 0.5.times.10.sup.6 or greater and
1.75.times.10.sup.6 or less. More preferably, a value of a ratio
(GIt/EIt) of the flexural rigidity value EIt to a torsional rigidity
value GIt of the shaft at a position 140 mm away from the tip on the head
side is specified to be 0.8.times.10.sup.-2 or greater and
1.2.times.10.sup.-2 or less.
