摘要：
A zirconia-base sintered body comprising a sintered substrate containing 30% by volume or more of tetragonal zirconia and a coating film disposed thereon, characterized in that the diffusion coefficient of oxygen in a material forming said coating film at no higher than 550.degree. C. is smaller than that of oxygen in said tetragonal zirconia at a temperature of no higher than said temperature.
