Abstract:
1. A method for manufacturing a honeycomb structure, said method comprising: extrusion-molding a raw material composition containing ceramic powder and a binder to manufacture a coupled honeycomb molded body having a shape in which a plurality of pillar-shaped honeycomb molded bodies are spaced apart from one another, each having a number of cells disposed in parallel with one another in a longitudinal direction with a cell wall therebetween, the pillar-shaped honeycomb molded bodies being integrated by interposing a coupling portion, the coupling portion being provided on a side face of each of said honeycomb molded bodies; firing the coupled honeycomb molded body to manufacture a coupled honeycomb fired body; cutting the coupling portion of the coupled honeycomb fired body to manufacture a plurality of coupling-portion-cut honeycomb fired bodies; and binding a plurality of honeycomb fired bodies by interposing an adhesive layer, at least one of the bound plurality of honeycomb fired bodies being a coupling-portion-cut honeycomb fired body, wherein the coupled honeycomb fired body has a shape in which two pieces of the pillar-shaped honeycomb fired bodies, each having a side face formed by at least two planes and a single curved face, are integrated with each other by interposing the coupling portion, the coupling portion being formed on a side face formed by the single curved face and having an approximately rectangular parallelepiped shape with longer sides approximately in parallel with the longitudinal direction.
