A pink-colored zirconia sintered body has a high sintered body density and strength, and a colored translucency, which has a color tone similar to teeth and excellent translucency and has high aesthetic properties. A colored translucent zirconia sintered body includes from 2 to 4 mol % of yttria, from 0.02 to 0.8 mol % of Er 2 O 3 , at least 20 and less than 2,000 ppm, as calculated as Fe 2 O 3 , of an iron compound, at least 0.005 and less than 0.2 wt % of Al 2 O 3 and the rest being zirconia, and having a lightness L* of from 55 to 75, a* of from 0 to 10 and b* of from 0 to 30 as chromatic parameters stipulated in JIS-Z8729, has a relative density of at least 99.80% and has a total light transmittance of at least 18% and at most 40% as measured at a sample thickness of 1 mm using a D65 light source. |
