Wood type golf club head
First Claim
1. A wood-type club head having (1) a center of gravity (G) defined by the distribution of weight in the club head, (2) a face with a sweet spot (SS) located where the face is intersected by a line perpendicular to the face extending through the center of gravity (G) of the club head, (3) a toe, (4) a heel and (5) a neck with a shaft insertion hole defining a shaft axis, wherein, in a state of the club head for performing measurements on the club head, the shaft axis is inclined at a set lie angle with respect to a horizontal plane and lies in a vertical plane, and a horizontal line tangent to the face at an area center of gravity (FC) of the face is parallel to the vertical plane, and wherein:
- the volume of the club head is in the range of from 350 cm3 to 500 cm3;
a distance (d) corresponding to a shortest distance between the shaft axis and the center of gravity (G) of the club head is in the range of from 45 mm to 50 mm;
a point (T) at which the horizontal line is intersected by a perpendicular line extending from the sweet spot (SS) of the face is located away from the area center of gravity (FC) and within 4 mm from the area center of gravity (FC) in the direction toward the heel.

Abstract
The invention provides a wood type golf club head, wherein in a measuring state where a center line of a shaft axis arranged within a vertical plane and is inclined at a set lie angle, and a face angle is set to zero, a distance (d) of center of gravity corresponding to a shortest distance between the center line of the shaft axis and a center of gravity (G) of the head is between 45 and 50 (mm), and a point (T) on which a horizontal tangential line passing through an area center of gravity (FC) of the face surface and being in contact with the face surface intersects a perpendicular line dropped to the tangential line from a sweet spot (SS) is arranged on the tangential line within 2 (mm) from the area center of gravity FC close to a toe, and within 4 (mm) close to a heel.
