There is provided a covering member for preventing erosion that has a high erosion resistance, is resistant to repeated thermal shocks so as to have a long life, and has a particular color allowing visual inspection of the surface layer for degradation. A covering member to be applied to a substrate made of an iron material or the like that will be eroded by contact with molten aluminum includes a Cr metal film as the lowest layer, a b layer formed of a CrN film, an intermediate layer, and an a layer formed of a TiSiN film, stacked in this order on the substrate. The intermediate layer includes layered films composed of the b layers and the a layers alternately stacked on top of one another.
