A honeycomb structure is provided which has an improved performance of exhaust gas purification. The honeycomb structure is an aggregate type honeycomb formed from a plurality of cells assembled together side by side laterally and cell walls isolating adjacent ones of the cells from each other by joining with a sealant layer (adhesive layer) or integral type honeycomb monolith, and a sealant layer (coating layer) provided on the outer surface of the aggregate type honeycomb or the integral type honeycomb monolith. The sealant layer (adhesive layer) or a sealant layer (coating layer) formedon the outer surface of aggregate type honeycomb or the integral type honeycomb monolith contains oxide particles, inorganic binder and a coloring agent. |
