<p>An object of the present invention is to provide a honeycomb structured body in which no cracks and the like occur even in case of thermal stress imposed in the regeneration process and the like, and the honeycomb structured body of the present invention is a honeycomb structured body in which a plurality of pillar-shaped honeycomb fired bodies are bound with one another by interposing a sealing material layer, each of the honeycomb fired bodies having a large number of cells longitudinally placed in parallel with one another with a cell wall therebetween, wherein an adhesive strength A between central portion honeycomb fired bodies out of the honeycomb fired bodies measured by a three-point bending strength test is at least 0.02 and at most 0.2 MPa, the central portion honeycomb fired bodies being positioned at a central portion of a cross-section formed by cutting the honeycomb structured body perpendicularly to the longitudinal direction, and the adhesive strength A is lower than an adhesive strength B between peripheral portion honeycomb fired bodies out of the honeycomb fired bodies measured by the three-point bending strength test, the peripheral portion honeycomb fired bodies forming a part of a periphery the honeycomb structured body.</p> |
