A puddle 21 composed mainly of a ceramic and/or a metal is molded to obtain a honeycomb molded material 22 ; the honeycomb molded material 22 is dried, or dried and fired to obtain a honeycomb carrier; there are formed, at two portions of each partition wall 3 of the honeycomb carrier, each present at a given site extending, along the axial direction of the honeycomb carrier, from the two end faces 8 and 9 of the carrier at which each cell 1 formed by each partition wall 3 is open, reinforced portions 11 having an erosion resistance at least larger than that of other partition wall portion, whereby a honeycomb intermediate structure 31 is produced; after or before loading of catalyst thereon, the honeycomb intermediate structure 31 is cut along the diameter direction; then, a catalyst is loaded as necessary to obtain a honeycomb catalyst. Thus, burden to operator is alleviated and there is efficiently obtained a honeycomb catalyst which is small in damage during production and deformation during firing and which is very small in pressure loss. |
