Abstract
A honeycomb structure includes a plurality of pillar-shaped honeycomb fired bodies bound with one another by interposing a adhesive layer. Each of the honeycomb fired bodies has a large number of cells longitudinally placed in parallel with one another with a cell wall therebetween. 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 are positioned at a central portion of a cross-section formed by cutting the honeycomb structure perpendicularly to the longitudinal direction. 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 form a part of a periphery the honeycomb structure.
