Beschreibung
Zusammenfassung:	A circumferential coating material contains colloidal silica, silicon carbide, and titanium oxide different in particle diameters from silicon carbide, coats a circumferential surface of a honeycomb structure 10 monolithically formed by extrusion , including as a main component, cordierite having a porosity of 50 to 75%, and forms a circumferential coating layer 20. A circumferentially coated honeycomb structure 30 has a honeycomb structure 10 comprising latticed porous partition walls 33 defining and forming a plurality of polygonal cells 32 forming through channels and extending from one end face 31a to the other end face 31b, and a circumferential coating layer 20 formed by coating at least a part of a circumferential surface 11 of the honeycomb structure 10 with the circumferential coating material.
