Abstract

A heat-resistant container according to the present disclosure includes a first wall portion constituting a sidewall and a second wall portion constituting an upper wall or bottom wall. The first wall portion and the second wall portion are made of a ceramic. The first wall portion has a large number of pores therein. In cross sections of the first wall portion, a porosity Pr1 is smaller than a porosity Pr2, where Pr1 is a porosity in a cross section of the first wall portion orthogonal to a wall surface of the first wall portion and parallel to a height direction of the first wall portion, and Pr2 is a porosity in a cross section of the first wall portion orthogonal to the wall surface of the first wall portion and parallel to a width direction of the first wall portion.
