ABSTRACT:
A ceramic honeycomb structural body for catalytic converters and filters for removing fine particles can be provided which is secured firmly in the catalytic converters with high reliability, minimum volume and small strength to external pressure without displacements and breakage thereof and a loss of expensive noble metals, by forming at least one step on the outer circumferential surface of the honeycomb structural body so as to form at least one recessed portion or protruded portion on the outer circumferential surface; the recessed portion or the protruded portion has a rough surface or is formed discontinuously to afford firm and safe holding of the ceramic honeycomb structural body in the vessel of the catalytic converter via a sealing member and/or a cushioning member.
