First claim
Opening claim text (preview).
The invention claimed is: 1. An ornamental component having an ornamental face which has an arithmetic mean surface roughness Ra of less than or equal to 0.03 μm in a roughness curve, comprising a titanium nitride sintered body containing nickel and niobium, the titanium nitride sintered body containing a compound comprising nickel, niobium and titanium, the ornamental face having a lightness index L* of greater than or equal to 65 but less than or equal to 71, a chromaticness index a* of greater than or equal to 4 but less than or equal to 8, and a chromaticness index b* of greater than or equal to 4 but less than or equal to 20 according to CIE 1976 L*a*b* color space. 2. The ornamental component according to claim 1 , wherein a content of free carbon is greater than or equal to 0.5 mass % but less than or equal to 1.2 mass % based on a total mass of all of constituents of the titanium nitride sintered body defined as 100 mass %. 3. The ornamental component according to claim 1 , wherein the titanium nitride sintered body contains chromium, and contains a compound comprising nickel and chromium. 4. The ornamental component according to claim 1 , wherein the titanium nitride sintered body contains at least one of molybdenum, tungsten and cobalt. 5. A watch, comprising the ornamental component according to claim 1 . 6. A portable terminal, comprising the ornamental component according to claim 1 . 7. A personal ornament, comprising the ornamental component according to claim 1 .
