Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a silicon carbide-based ceramic porous material, of which the diameters of pores are less than 500 μm and the sizes and distribution of the diameters of pores are comparatively even, and its manufacturing method. SOLUTION: The silicon carbide-based ceramic porous material is formed by monoaxially compression-molding sponges comprising polyurethane, polyethylene or rubber, wherein a carbonized porous body formed by baking and carbonizing sponge-shaped porous body formed by impregnating the sponges with a slurry containing resins and silicon powder, or a slurry containing resins, silicon powder and silicon carbide powder, is reacted and sintered with silicon, or melt-impregnated with silicon after being reacted and sintered with silicon, and the silicon carbide-based ceramic porous material has open cells within the range of pore diameters of 0.1 μm or larger and smaller than 500 μm.
