PROBLEM TO BE SOLVED: To provide a method for producing a honeycomb structure, in which 'a nest' is prevented from being formed in an adhesive material layer so that the honeycomb structure having high adhesive strength can be produced.SOLUTION: The method for producing the honeycomb structure comprises the steps of: preparing a honeycomb fired body which has end faces each including cell partition walls for dividing/forming a plurality of cells becoming flow passages of a fluid and has joint surfaces or side faces being the outer periphery of a honeycomb assembly; arranging the adhesive material layer comprising adhesive material paste containing an inorganic particle and an inorganic fiber in the space between the adjacent side faces; and drying the honeycomb assembly obtained by binding a plurality of adjacent honeycomb fired bodies to each other while interposing the adhesive material layer therebetween to prepare a ceramic block. At the step of drying the honeycomb assembly, the honeycomb assembly is dried in such a state that the adhesive material layers on the side faces of the honeycomb assembly and those on the end faces thereof are covered with moisture-impermeable members 23, 24 having openings 24b arranged correspondingly to the end face of the honeycomb fired body. |
