Abstract
A honeycomb structurecomprising a honeycomb segment bonded bodyhaving a number of honeycomb segmentsintegrated on each bonding planes via bonding material layershas a structure so that a number of cellsproviding fluid flow channels are disposed in parallel in the direction of center axis thereof. The honeycomb structureis constructed so that the porosity of an outer portion of the bonding material layers(an area from the interface with the honeycomb segment-bonding plane to a point apart from that interface by a distance equivalent to 20% of the entire layer thickness) is smaller than the porosity of a central portion located inward of the outer portion, and so that the bonding material layershave a compression Young's modulus along the Z-axis of 5 to 100 MPa.
