To accurately visualize for a trainer the movement of a golf club and the movement of the body such as the arms, hands, the upper part of the body, and the feet by means of laser beams, through the entire process of swing from address, take-back, down-swing, and up to the completion of follow- through.

This golf swing practicing tool is made up of a grip 2 incorporated with a power source 12 and a laser emitter 13, a base-end side laser emitting part 3 provided to the base end side of the grip 2 for emitting laser beams in the same direction as the longitudinal axis of the grip 2, and a fore- end side laser emitting part 6 provided to a head 4 connected to the fore-end side of the grip 2 and having a face 5. The fore-end side laser emitting part 6 is made up of a perpendicular directional laser beam emitting part 17 provided for emitting laser beams in the perpendicular direction to the face surface, and a longitudinal axial directional laser beam part 19 provided for emitting laser beams in the extended direction of the longitudinal axes of the grip 2 and the head 4.
