A wood club head is provided to hit a golf ball at the oblique loft angle in the impact sweep track in using a long hosel and to fly a golf ball easily without blowing away the golf ball, by keeping ZG(Centroid Depth) and FP(Face Progression) values low. In a wood club head having the loft angle over 13 degrees, the length of a hosel(2) is over 20mm. FP is set within a range of 12~16mm. ZG is set within a range of 20~25mm. A golfer makes a golf ball fly easily by using the long hosel, but the golf ball is not flown away. The length of the hosel is below 20mm. FP is set within a range of 16~20mm. ZG is set within a range of 25~30mm. The ball is not flown well as the loft angle is set erectly due to the impact down-blow track, by using the short hosel. But, the golf ball spins well by increasing a ZG value.
