Claim 1:
2. The zirconia-based porous body according to claim 1, wherein
when a pore volume in an entire pore distribution range after heating at 1150° C. for 12 hours under atmospheric pressure is defined as pore volume C and a pore volume in an entire pore distribution range before heating is defined as pore volume D,
the pore volume C is 0.40 ml/g or more and 1.50 ml/g or less, and
a pore volume retention ratio Y in an entire pore distribution range represented by formula (2) below is 30% or more and 95% or less:

<Pore volume retention ratioY in entire pore distribution range>[(Pore volumeC)/(Pore volumeD)]×100  Formula (2).
