Abstract
A honeycomb structure obtained by bonding, into one piece, a plurality of honeycomb segments () each having a plurality of passages () surrounded by cell walls and extending in the axial direction of the segment. In the honeycomb structure, a material A () having compressive elasticity is provided between a side surface () of at least one honeycomb segment [2()] not constituting the outermost peripheral surface () of the honeycomb structure () and a side surface of the honeycomb segment [(2()) adjacent thereto. A honeycomb structure assembly () obtained by providing a material B () having compressive elasticity on the outermost peripheral surface () of the honeycomb structure () in a compressed state and thereby compression-holding the resulting honeycomb structure in a metallic container (). A honeycomb structure using materials having compressive elasticity (B) is resistant to breakage, and has superior durability and reliability, by reducing the thermal stress generated therein during use by a sharp temperature change of inflow gas, a local heat of reaction and a local heat of combustion.
