Patent ID: 6875130

Claim:
A wood-type golf club head having a head volume of not less than 320 cc, a gravity point distance in a range of from 25 to 35 mm, a sweet spot height in a range of from 28 to 40 mm, and a heel area width in a range of from 40 to 45% of a club head width, wherein under a measuring state of the club head set on a horizontal plane such that a shaft axis inclines within a vertical plane at its lie angle and an angle between the vertical plane and a horizontal tangential line to the centroid of a clubface forms its face angle, the gravity point distance is defined as the distance of a point which is a projection of the gravity point of the club head on the vertical plane, measured from the shaft axis, the sweet spot height is a height from the horizontal plane of a sweet spot which is a point of intersection between the clubface and a line normal to the clubface drawn from the gravity point, the heel area width is defined as the distance between a heel point and a rear end point measured in parallel with the vertical plane, the heel point is a projection of a heel end on the horizontal plane, the heel end is a point on the vertical plane which is farthest from the shaft axis in a direction at a right angle to the shaft axis towards the heel, the rear end point is a point on a projective profile line which is farthest from the vertical plane towards the backside of the club head, the horizontal projective profile line is the profile line of the club head projected on the horizontal plane, the club head width is the distance between the heel point and a toe point measured in parallel with the vertical plane, and the toe point is an extreme end of the horizontal projective profile line, on the toe side thereof, in a direction parallel to the vertical plane.
