PROBLEM TO BE SOLVED: To further ensure the use of SiC foam particularly within a muffler or particularly for the purpose of regeneration thereof by significantly improving the mechanical properties without making the specific surface area or the catalyst properties including a dual porosity mode disadvantageous, while maintaining the permeability of SiC foam medium. SOLUTION: A silicon carbide foam for use as a catalyst medium is obtained by impregnating an organic foam with a silicon suspension in a resin to which a hardening agent has been added, incomplete cross-linking of the resin, carbonizing the organic foam and the resin, and vaporizing the silicon, which has high specific surface area of at least 5 m<SP>2</SP>/g and improved mechanical properties including compressive strength of more than 0.2 MPa.
