ABSTRACT:
A honeycomb structural body includes a ceramic block having a flat shape and including honeycomb units bonded to each other through a sealing material layer, each of the honeycomb units made of porous ceramic and having through holes extending in parallel with one another in a longitudinal direction of the ceramic block and a partition wall interposed between the through holes. The honeycomb structural body further includes a peripheral sealing material layer formed on a peripheral portion of the ceramic block. The sealing material layer is formed such that the sealing material layer abuts against the peripheral sealing layer at an angle in a diagonal direction with respect to a major axis of a contour of the ceramic block in a cross section perpendicular to the longitudinal direction.
