Abstract
A honeycomb structured body of the present invention is a pillar-shaped honeycomb structured body comprising a large number of through holes that are longitudinally placed in parallel with one another with a partition wall therebetween, wherein the large number of through holes include a group of large-capacity through holes being sealed at one of end portions so that the sum of areas on a cross section perpendicular to the longitudinal direction is made relatively larger, and a group of small-capacity through holes being sealed at the other end portion so that the sum of areas on the cross section is made relatively smaller, and the partition wall that separates the adjacent through holes constituting the group of large-capacity through holes is provided with a selective catalyst supporting portion used for selectively supporting a catalyst.
