The invention provides a method for forming the metal appearance of a sporting product and can stably foms a stereo metal appearance at low cost. In particular, the method is to stereoly form a decoration layer containing a metal materal on the surface of a base material (10) of the sporting product and comprises an adhesive formation process and a metal material formation process, wherein in the adhesive formation process, the surface of the base material (10) is provided with multiple uv-curing type adhesive layers (31), (32), (33) in a way that one part of the adhersive layer at a lower side is exposed through ink jet printing; and in the metal material formation process, metla material layers (41), (42), (43) are formed on the multiple uv-curing type adhesive layers (31), (32), (33).
