Abstract:
1. A honeycomb structure comprising: a plurality of pillar-shaped honeycomb fired bodies bound with one another by interposing an adhesive 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 about 0.02 and at most about 0.2 MPa, the central portion honeycomb fired bodies being positioned at a central portion of a cross-section formed by cutting the honeycomb structure perpendicularly to the longitudinal direction, and wherein 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 structure.
