Abstract
A honeycomb structural body which is capable of increasing the limiting collection amount of particulate, reducing the pressure loss in use, and reducing fluctuations in the pressure loss even if the flow rate from an internal combustion engine of exhaust gases fluctuates. The honeycomb structural body is a columnar honeycomb structural body in which a large number of through holes are arranged side by side in the length direction with a partition wall interposed therebetween. The large number of through holes are constituted by a group of large-capacity through holes, with one end thereof sealed to make the total cross-sectional areas perpendicular to the length direction relatively greater, and a group of small-capacity through holes, with the other end thereof sealed to make the total cross-sectional areas relatively smaller. The honeycomb structural body includes a plurality of columnar porous ceramic members.
