PROBLEM TO BE SOLVED : To provide a zirconia sintered compact free from contaminating a contact material by an impurity element, having excellent thermal shock resistance (particularly the thermal shock resistance in quick heating up to 1, 800°C) and high mechanical strength. SOLUTION : (1) A zirconia raw material prepared by mixing ZrO2 highly purified to contain ≤0.3 wt.% total inevitable impurity except HfO2 with one or more kinds selected from rare earth metal oxides and/or alkaline earth metal oxides used as the stabilizer of a ZrO2 high temperature crystal phase and heating the mixture to a temperature equal to or above the melting point to pass through a molten state is sintered under a specific condition to obtain the zirconia sintered compact. (2) A zirconia raw material prepared by mixing ZrO2 highly purified to contain ≤0.3 wt.% total inevitable impurity except HfO2 and heated to a temperature equal to or above the melting point to pass through a molten state with one or mare kinds selected from rare earth metal oxides and/or alkaline earth metal oxides used as the stabilizer of a ZrO2 high temperature crystal phase is sintered under a specific condition to obtain the zirconia sintered compact.
