To manufacture a vehicular wheel having such high designability that a part where a cut surface and a surface of a base material cross each other is visually emphasized.SOLUTION: A method for manufacturing a vehicular wheel includes a wheel rim having a substantially cylindrical shape, and a wheel disk provided on an inner peripheral side of the wheel rim. The method includes: a molding step of molding a base material of a light metal-made wheel by a casting method or forging method; a cutting step of cutting the partial base material, and forming a cut surface; a coating step of coating the cut surface, an edge part where the cut surface and the surface of the base material cross each other, and the periphery of at least the edge part on the surface of the base material with a color coating material; and a chamfering step of chamfering the edge part, and forming a bright surface to which the base material is exposed, after the coating step.SELECTED DRAWING: Figure 5 【課題】切削面と素材の表面とが交わる部分が視覚的に強調された意匠性の高い車両用ホイールを製造する。【解決手段】車両用ホイールの製造方法は、略円筒状のホイールリムと、ホイールリムの内周側に設けられるホイールディスクと、を備える車両用ホイールの製造方法である。同製造方法は、鋳造法または鍛造法により軽金属製のホイールの素材を成形する成形工程と、素材の一部を切削加工して切削面を形成する切削工程と、切削面と、該切削面と素材の表面とが交わるエッジ部と、素材の表面のうちの少なくともエッジ部の周囲と、を有色の塗料で塗装する塗装工程と、塗装工程後、エッジ部に対して面取り加工を施して素材が露出した光輝面を形成する面取り工程と、を含む。【選択図】図５
