In a method of manufacturing a honeycomb structured body, a ceramic block is formed by binding multiple pillar-shaped honeycomb fired bodies with adhesive layers interposed therebetween. The multiple pillar-shaped honeycomb fired bodies are bound on a support by piling up the multiple pillar-shaped honeycomb fired bodies successively. A placing position where a primary honeycomb fired body is to be placed is determined. A position of an end face of at least one secondary honeycomb fired body is fixed by applying force to the end face of the at least one secondary honeycomb fired body. The primary honeycomb fired body is placed on the placing position with the position of the end face of the at least one secondary honeycomb fired body being fixed. The fixing further includes first positioning or second positioning based on a number of the at least one secondary honeycomb fired body before the fixing.

Method of manufacturing honeycomb structured body

A honeycomb structure includes a ceramic block. A plurality of honeycomb fired bodies include first-shaped units, second-shaped units, and third-shaped units. The first-shaped units include peripheral first-shaped units. Each of the peripheral first-shaped units is disposed in such a manner as to have two sides. One side of the two sides faces one of adjacent sides of one third-shaped unit among the third-shaped units with an adhesive layer therebetween. Another side of the two sides faces one of adjacent sides of another third-shaped unit among the third-shaped units with the adhesive layer therebetween. The two sides of each of the peripheral first-shaped units or extensions of the two sides are each neither substantially parallel nor substantially perpendicular to an extension of a second side and an extension of a first side of each of the second-shaped units.

Honeycomb structure

A honeycomb structure includes a ceramic block including honeycomb fired bodies. The honeycomb fired bodies include an assembly including a plurality of substantially quadrangular-cross-section units which are combined with one another with an adhesive layer interposed between the plurality of substantially quadrangular-cross-section units. A peripheral face of the assembly of substantially quadrangular-cross-section units has a concave portion and a convex portion formed in a substantially step-shaped pattern. At least one substantially triangular-cross-section unit has an outer wall on a periphery portion of the at least one substantially triangular-cross-section unit. The at least one substantially triangular-cross-section unit is fit in the concave portion with the adhesive layer interposed between the at least one substantially triangular-cross-section unit and the concave portion. A sealing material layer is provided on a peripheral face of the ceramic block. The sealing material layer has partially different thickness.
