A honeycomb structure obtained by bonding, into one piece, a plurality of honeycomb segments ( 2 ) each having a large number of passages ( 6 ) surrounded by cell walls and extending in the axial direction of the segment. In the honeycomb structure, a material A ( 3 ) having compressive elasticity ( 3 ) is provided at least at a portion of the gaps formed by each two faces of adjacent honeycomb segments ( 2 ), close to each other. A honeycomb structure assembly ( 8 ) obtained by providing a material B ( 5 ) having compressive elasticity on the outer peripheral portion of the above honeycomb structure in a compressed state and thereby compression-holding the honeycomb structure in a metallic container ( 11 ). The honeycomb structure and the honeycomb structure assembly have good durability to a heat or a vibration, applied during their use. |
