An object of the present invention is to provide a honeycomb structural body, which has a flat shape, makes its sealing material layer less likely to be damaged at increased temperatures, maintains high bonding strength, and is superior in resistance to physical impact, and the honeycomb structural body of the present invention is a honeycomb structural body comprising: a ceramic block having a flat shape in which a plurality of honeycomb units are bonded each other through a sealing material layer, said honeycomb unit is mainly composed of porous ceramic and includes a large number of through holes placed in parallel with one another in a length direction with a partition wall interposed therebetween; and
a sealing material layer formed on a peripheral portion thereof, wherein the sealing material layer among the honeycomb units on a cross section perpendicular to the length direction have a pattern that is formed in a diagonal direction with respect to the major axis of the shape forming the contour of the cross section. |
