Disclosed a hybrid golf shaft in which one or more aramid fiber containing prepregs (H) are laminated in a length section of 5 cm or more of the whole length of the golf shaft, and three or more carbon fiber prepregs (C) are laminated in a length section of 50 cm or more of the whole length of the golf shaft. The golf shaft is configured in that aramid prepregs (H) or hybrid prepregs (H) with excellent impact absorbability are arranged in a length section of 5 to 50 cm from a thin end of the golf shaft or along the whole length (L) in an axial direction of the golf shaft, to thereby effectively reduce the number of vibrations in the golf shaft when the golf ball is hit.
