Provided is a rigid decorative member that has high film hardness, is excellent in scratch resistance performance and abrasion resistance performance, and has excellent color brightness and color saturation. The rigid decorative member of the present invention is a rigid decorative member wherein a reaction compound film of an alloy of Cr and a metal selected from one or two or more of Mo, W, Nb, Ta, Ti, Hf, Zr, and V, and of a non-metallic element selected from one or two or more of nitrogen, carbon, and oxygen is formed on a substrate. There is provided the rigid decorative member significantly improved in scratch resistance and abrasion resistance and having a color tone with a high quality feel; and there is further supplied a product of which the color tones of brightness and color saturation can be freely controlled. The rigid decorative member of the present invention includes the reaction compound film of the alloy of Cr, which is a metal having high adhesion to a metal and high brightness but having low hardness, and a metal having high film hardness and high corrosion resistance but having low brightness and low adhesion (Mo, W, Nb, Ta, Ti, Hf, Zr, V), and of the non-metallic element such as nitrogen, carbon, or oxygen.
