<p>An object of the present invention is to provide a flat-shaped honeycomb structured body in which sealing material layers are hardly damaged during use and in which adhesion strength can be maintained. The honeycomb structured body of the present invention is a honeycomb structured body including: a honeycomb block which has a flat-shaped cross section and has a structure in which plural honeycomb units are bonded to one another through sealing material layers, each unit including as amain component a porous ceramic and having in the longitudinal direction a number of cells placed in parallel with a cell wall therebetween; and a sealing material layer provided on an outer peripheral portion of the honeycomb block. Herein, each honeycomb unit contains inorganic fibers and/or whiskers in addition to inorganic particles, and the sealing material layer between the honeycomb units on the cross section perpendicular to the longitudinal direction is formed such that the direction thereof is diagonal to the major axis of a shape constituting the contour of the cross section.</p> |
