ハニカム構造体

Japanese Patent JPWO2008105082

A1

An object of the present invention is to provide a honeycomb structured body having a structure in which a ceramic block formed by combining a plurality of honeycomb fired bodies (20), each having an outer wall (23) on the periphery of cells, with one another, has a sealing material layer formed on the peripheral face thereof, wherein the sealing material layer is less likely to be separated from the ceramic block even after having been used repeatedly as a filter for purifying exhaust gases. The honeycomb structured body of the present invention comprises: a structure in which a plurality of pillar-shaped honeycomb fired bodies (20), each having a large number of cells (21) longitudinally disposed in parallel with one another with a cell wall (22) therebetween and an outer wall (23) formed on a periphery of the large number of cells, are combined with one another by interposing an adhesive layer and a sealing material layer is formed on a peripheral face of the combined ceramic blocks, wherein out of the outer walls of the honeycomb fired bodies, an outer wall forming one portion of the peripheral face of the ceramic block has a protruding portion (24) on a surface of the outer wall (23), and the protruding portion (24) is made from the same material as the material of the outer walls.
