An object of the present invention is to provide a honeycomb structural body for use in a filter, which can support a large amount of catalysts, can suppress increase in pressure loss upon collecting particulates, can have a high particulate collecting capability and can efficiently carry out a regenerating process and a toxic gas purifying process. The honeycomb structural body according to the present invention is a pillar-shaped honeycomb structural body having a structure in which a plurality of through holes are placed in parallel with one another in the length direction with a partition wall interposed therebetween, wherein lamination members are laminated in the length direction so that the through holes are superposed on one another, and one of ends of each through hole is sealed. |
