<p>An object of the present invention is to provide a honeycomb structured body in which a temperature distribution between the center portion and the peripheral portion tends not to occur and unburned particulates tend not to remain upon carrying out a regenerating process. The honeycomb structured body of the present invention comprises: a plurality of pillar-shaped honeycomb fired bodies, each having a large number of cells that are placed in parallel with one another in a longitudinal direction with a cell wall interposed therebetween, that are combined with one another with an adhesive layer interposed therebetween, wherein the honeycomb fired bodies include a center-portion honeycomb fired body located in the center portion and a peripheral-portion honeycomb fired body located in a peripheral portion in a cross section perpendicular to the longitudinal direction of the honeycomb structured body, a shape of the center-portion honeycomb fired body is a rectangular shape in the cross section, an area of the center-portion honeycomb fired body is 900 to 2500 mm 2 in the cross section, a shape of the peripheral-portion honeycomb fired body is different from the shape of the center-portion honeycomb fired body in the cross section, and an area of the peripheral-portion honeycomb fired body is 0.9 to 1.3 times larger than the area of the center-portion honeycomb fired body in the cross section.</p> |
