<p>A honeycomb structured body of the present invention is a honeycomb structured body including: a ceramic block formed by a plurality of 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 placed in parallel with one another in a longitudinal direction with a cell wall therebetween; and a sealing material layer formed on a peripheral face of the ceramic block,
wherein
the honeycomb fired bodies comprise first-shaped units, second-shaped units, and third-shaped units,
each of the first-shaped units has a quadrangular shape in a cross section perpendicular to the longitudinal direction,
each of the second-shaped units has a shape that includes at least a first side, a second side longer than the first side and making a right angle with the first side, and an inclined side facing the right angle in the cross section perpendicular to the longitudinal direction,
each of the third-shaped units has a right triangular shape with a hypotenuse and adjacent sides in the cross section perpendicular to the longitudinal direction,
each of the second-shaped units is disposed in a peripheral portion of the ceramic block in such a manner that the inclined side is in contact with the sealing material layer,
each of the third-shaped units is disposed on the inner side of the second-shaped units in the ceramic block in such a manner that the hypotenuse faces the second side of any one of the second-shaped units with the adhesive layer therebetween,
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 facing one of the adjacent sides of one third-shaped unit with the adhesive layer therebetween, the other side facing one of the adjacent sides of another third-shaped unit with the adhesive layer therebetween and
the two sides of each of the peripheral first-shaped units or extensions thereof are each neither parallel nor perpendicular to an extension of the second side and an extension of the first side of each of the second-shaped units.</p> |
