    摘要: An object of the present invention is to provide a honeycomb structural body (filter) which has a low pressure loss upon collecting particulates, makes it possible to deposit a great amount of particulates and ashes, and is less likely to produce cracks. The columnar honeycomb structural body of the present invention includes a plurality of through holes placed in parallel with one another in the length direction, and wall portion that separates the plurality of through holes from one another and constitutes a circumferential face, wherein the plurality of through holes are composed of a group of large-capacity through holes, with one end thereof being sealed so as to cause the total of areas of cross-section perpendicular to the length direction to become relatively greater, and a group of small-capacity through holes, with the other end thereof being sealed so as to cause the total of areas of the above-mentioned cross-section to become relatively smaller, and the above-mentioned circumferential face of the columnar honeycomb structural body has a chamfered corner portion.
