<p>An object of the present invention is to provide a honeycomb structured body that can prevent damage due to a thermal stress, and has a high thermal shock resistance, and the honeycomb structured body of the present invention comprises a plurality of pillar-shaped honeycomb fired bodies combined with one another with an adhesive layer interposed therebetween, each of the honeycomb fired bodies having a large number of cells longitudinally placed in parallel with one another with a cell wall interposed therebetween, wherein the honeycomb fired bodies include a center-portion honeycomb fired body located in a center portion of a cross-section taken perpendicular to the longitudinal direction of the honeycomb structured body, and periphery honeycomb fired bodies that form a part of a periphery of the cross-section, the periphery honeycomb fired bodies include at least a single piece of a periphery small honeycomb fired body having a cross-sectional area in the cross-section of less than 60% of a cross-sectional area of a single piece of the center-portion honeycomb fired body, a cross-sectional area of a periphery honeycomb bonded body in the cross-section is 60% or more of the cross-sectional area of a single piece of the center-portion honeycomb fired body, the periphery honeycomb bonded body formed by bonding the periphery small honeycomb fired body and at least a single piece of an other honeycomb fired body with an adhesive layer B interposed therebetween, and the adhesive layer B has higher thermal conductivity and higher Young' s modulus than those of an adhesive layer A, the adhesive layer A being defined as an adhesive layer bonding the center-portion honeycomb fired bodies to one another.</p> |
