Claim 0:
1. A silicon carbide ceramic honeycomb structure having large numbers of axially penetrating flow paths partitioned by porous silicon carbide cell walls,
said cell walls comprising silicon carbide particles as aggregate and binder layers for binding said silicon carbide particles, and containing no metallic silicon,
said binder layer consisting of a cordierite phase and a spinel phase, or consisting of a cordierite phase, a spinel phase, and at least one optional component selected from the group consisting of cristobalite, mullite and forsterite,
the molar ratio M1 of said cordierite phase [=cordierite phase/(cordierite phase+spinel phase)] being 0.4-0.9,
the porosity of said cell walls being 38-50%, and
the median pore diameter of said cell walls being 5-20 μm.
