Abstract
A honeycomb structure is manufactured by molding a pillar-shaped honeycomb molded body having a large number of cells disposed in parallel with one another in a longitudinal direction with a cell wall therebetween by extrusion-molding a raw material composition including a ceramic powder and a binder, and carrying out a firing treatment on the honeycomb molded body to manufacture a honeycomb fired body. A plurality of the honeycomb fired bodies are provided, and both end faces of each of the plurality of the honeycomb fired bodies are hold with a holding member after positioning the plurality of the honeycomb fired bodies on a predetermined position. An adhesive paste is injected into a gap between the plurality of honeycomb fired bodies held on the predetermined position. The adhesive paste is dried and solidified to form an adhesive layer.
