    Zirconia sintered body having similar appearance to natural tooth. On straight line extending in first direction from one end to the other end of zirconia sintered body, when chromaticity (L*, a*, b*) by a L*a*b* colorimetric system of first point positioned in section from the one end to 25% of the whole length is (L1, a1, b1) and chromaticity (L*, a*, b*) by L*a*b* colorimetric system of second point positioned in section from the other end to 25% of whole length is (L2, a2, b2), L1 ranges from 58.0 to 76.0, a1 ranges from −1.6 to 7.6, b1 ranges from 5.5 to 26.3, L2 ranges from 71.8 to 84.2, a2 ranges from −2.1 to 1.8, b2 ranges from 1.9 to 16.0, L1a2, b1>b2, and tendency to increase or decrease chromaticity by the L*a*b* colorimetric system from first point to second point does not change.
