ABSTRACT:
A ceramic porous body is provided, inclusing a plurality of pores formed in a ceramic substrate at a specified porosity. A pore part is discriminated from a non-pore part by binarizing a cross-sectional plane image of the substrate by image analysis. When a center line passing the central part of the pore part is drawn, the porosity (ε (%)), a mean width (DP(μm)) of the pore part represented by a mean value of a distance, between outlines specifying the pore part, perpendicular to the center line, a mean length (L (μm)) of the pore part represented by a mean value of a length of the center line between adjacent branch points and a length of the center line between an end of the center line and the branch point, and a mean pore size (DH(μm)) satisfy a specified relationship.
