A wood-type golf club having a head disposed at a tip end of a shaft, a grip disposed at a butt end of the shaft, and a butt partial layer having a weight Wa that is disposed in a butt range extending from the shaft butt end to a point separated from the butt end by 250 mm, wherein
- the weight of the golf club is not larger than 340 g,
- the product of a ratio (head weight /club weight) of the head weight to the club weight, and a ratio (LG/LS) of the distance LG from the tip end of the shaft to the center of gravity of the shaft to the full length LS of the shaft, is not smaller than 0.365, and
- if the weight of the shaft in said butt range is represented as Wb, then Wa/Wb is not lower than 0.4 but not higher than 0.7.
