Embodiments disclosed herein relate to a billiard cue and a manufacturing method, and more particularly to a billiard cue and the method of manufacturing the outer shell member is fixed to the inclined surface formed on the outer peripheral surface of the core member.

Generally, a billiard is a sport in which a player plays a score on a billiard table by playing a cue ball on a cue table, forming a bridge with one hand, fixing the cue, and applying a force to the cue with another hand to hit the billiard ball.

The billiard cue may be composed of a lower base forming a handle portion and a counterpart forming a hitting portion of the billiard ball.

Here, the base and the counterpart are mainly made of wood and may be made of a single piece, but are usually configured to be fastened in a structure that can be separated from each other in a prefabricated manner.
