ABSTRACT:
A honeycomb structure1comprising a honeycomb segment bonded body10having a number of honeycomb segments2integrated on each bonding planes via bonding material layers9has a structure so that a number of cells5providing fluid flow channels are disposed in parallel in the direction of center axis thereof. The honeycomb structure1is constructed so that the porosity of an outer portion of the bonding material layers9(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 layers9have a compression Young's modulus along the Z-axis of 5 to 100 MPa.
