Claim:
A method for manufacturing a honeycomb structure, the method comprising: molding a ceramic raw material to manufacture a honeycomb molded body having a plurality of cells longitudinally disposed substantially in parallel with one another with a cell wall between the cells; firing said honeycomb molded body to manufacture a honeycomb fired body; and bonding a plurality of said honeycomb fired bodies to manufacture a ceramic block by placing a cavity-holding member between side faces of said honeycomb fired bodies, forming an adhesive paste layer, and then, solidifying the adhesive paste layer by heating, wherein said cavity-holding member has a substantially rectangular pillar shape and has a substantially same thickness as a thickness of the adhesive paste layer, wherein said cavity-holding member comprises a nonflammable material which is nonflammable at a temperature of about 700° C., the nonflammable material comprising a fibrous paper or an inorganic material sheet each comprising fibers and inorganic particles, wherein the cavity-holding member has Young's modulus of at least about 0.001 GPa and at most about 0.02 GPa, wherein the cavity-holding member has a density of at least about 0.8 g/cm 3 and at most about 2.0 g/cm 3 , wherein the material of the cavity-holding member is a different material from that of the adhesive paste layer, wherein said fibers contained in the cavity-holding member are selected from a group consisting of zirconia fibers, calcium silicate fibers, magnesium silicate fibers, rock wool, and wherein the adhesive paste layer includes inorganic fibers selected from a group consisting of silica-alumina fibers, mullite fibers, alumina fibers and silica fibers.
