Honeycomb structured body and method of manufacturing the honeycomb structured body

摘要

An object of the present invention is to provide a honeycomb structured body which is not easily broken at the interface between the adhesive layer and the sealing material layer even after heat cycles such as regeneration process are repeated over a long period of time, and the honeycomb structured body of the present invention comprises a ceramic block formed by bonding a plurality of pillar-shaped honeycomb fired bodies by interposing an adhesive layer therebetween, and a sealing material layer provided on the periphery of the ceramic block, each of the honeycomb fired bodies having a large number of cells disposed in parallel with one another in a longitudinal direction with a cell wall therebetween, wherein the adhesive layer and the sealing material layer are integrally formed with no interface to divide the two layers.
