Abstract
A honeycomb structure wherein a plurality of honeycomb segments (1) each having a large number of through-holes surrounded by partition walls and extending in the axial direction of the segment are bonded at the sides of the honeycomb segments (1) parallel to said axial direction (X) and integrated, the honeycomb structure being characterized in that, in its section perpendicular to said axial direction (X), the shortest distance (L1) from the gravity center of the section to the bonded areas (5) of honeycomb segments in the section is 1/10 or less of the largest distance (L2) from the gravity center of the section to the circumference (9) of the section. This honeycomb structure hardly generates cracks caused by the thermal stress appearing therein during the use and is superior in durability.
