PROBLEM TO BE SOLVED: To provide a honeycomb structure capable of preventing catalyst slurry from seeping out to an outside surface of an outer peripheral wall, improving the strength of the outer peripheral wall, and consequently, also improving the isostatic strength of the whole structure.SOLUTION: A honeycomb structure 1 includes: a honeycomb base material 2 having porous partitions 4 for partitioning the structure into multiple cells 5 extending from an inlet end surface 11 to be an entrance of fluid, to an outlet end surface 12 to be an exit of the fluid, and a porous outer peripheral wall 6 formed integrally with the partitions 4; and a coating layer 3 provided on at least a part of an outside surface of the outer peripheral wall 6. A part of the coating layer 3 enters pores of the outer peripheral wall 6, and a thickness of the part of the coating layer 3 entering the pores of the outer peripheral wall 6 is 1-90% of a thickness of the outer peripheral wall 6.SELECTED DRAWING: Figure 1 |
