Zusammenfassung:	To provide a vanadium silicate nitride film-coated member having improved durability, wherein, in order to extend a product life by showing a function as a vanadium silicate nitride film over a long period, improvement of durability as the vanadium silicate nitride film-coated member is required by suppressing peeling of the vanadium silicate nitride film.SOLUTION: A vanadium silicate nitride film-coated member 1 includes a steel stock 2 having a nitrided layer 2a on the surface, and a vanadium silicate nitride film 3 formed on the nitrided layer 2a, and has a constitution in which a critical load in a scratch test is 65 N or higher.SELECTED DRAWING: Figure 1 【課題】珪窒化バナジウム膜としての機能をより長期にわたって発揮させて製品寿命を延ばすためには、珪窒化バナジウム膜の剥離を抑え、珪窒化バナジウム膜被覆部材としての耐久性を向上させることが必要である。したがって、耐久性を向上させた珪窒化バナジウム膜被覆部材を提供する。【解決手段】表面に窒化層２ａを有する鋼材２と、窒化層２ａの上に形成された珪窒化バナジウム膜３と、を備え、スクラッチ試験における臨界荷重が６５Ｎ以上である、珪窒化バナジウム膜被覆部材１を構成する。【選択図】図１
