The honeycomb structured body of the present invention includes a ceramic block formed by combining a plurality of honeycomb fired bodies with an adhesive layer interposed between, the honeycomb fired bodies each having a large number of cells and surrounded by peripheral walls, the cells longitudinally placed in parallel with one another with a cell wall therebetween, wherein the honeycomb fired bodies of the ceramic block have different shapes, the honeycomb fired bodies include outer honeycomb fired bodies located in a peripheral part of the ceramic block and at least one inner honeycomb fired body located inward of the outer honeycomb fired bodies, at least one of the outer honeycomb fired bodies includes at least a curved part and a linear part in a part of a periphery which partially constitutes the periphery of the ceramic block, in a cross-section of the at least one of the outer honeycomb fired bodies perpendicular to the longitudinal direction, the linear part of each of the at least one of the outer honeycomb fired bodies is parallel to at least one of the adhesive layer between the outer honeycomb fired body and an adjacent inner honeycomb fired body, and the adhesive layer between the outer honeycomb fired body and an adjacent outer honeycomb fired body, and the linear part of each of the at least one of the outer honeycomb fired bodies has a length of 5 to 20 mm. |
