<p>An object of the present invention is to provide a honeycomb structured body which can prevent the damage to the honeycomb structured body caused by the force applied to a radial direction and also has a low heat capacity, and the honeycomb structured body comprises a plurality of pillar-shaped honeycomb fired bodies combined with one another by interposing an adhesive layer therebetween, each of the honeycomb fired bodies having a large number of through holes, which are longitudinally formed in parallel with one another and divided by a partition wall, wherein
the honeycomb fired bodies comprise inorganic particles and an inorganic binder,
the honeycomb fired bodies include a center-portion honeycomb fired body located in a center portion and a peripheral-portion honeycomb fired body located in a peripheral portion in a cross section perpendicular to the longitudinal direction,
the center-portion honeycomb fired body has a square cross-sectional shape perpendicular to the longitudinal direction of the honeycomb structured body,
the center-portion honeycomb fired body has an area of 2500 to 5000 mm 2 in the cross-section,
a cross-sectional shape perpendicular to the longitudinal direction of the peripheral-portion honeycomb fired body is different from a cross-sectional shape perpendicular to the longitudinal direction of the center-portion honeycomb fired body, and
a cross-sectional area perpendicular to the longitudinal direction of the peripheral-portion honeycomb fired body is 0.9 to 1.3 times larger than a cross-sectional area perpendicular to the longitudinal direction of the center-portion honeycomb fired body.</p> |
