Abstract:
1. A honeycomb structure, comprising: a plurality of honeycomb units bonded together by using a sealing material layer, each of the honeycomb units including a plurality of through holes arranged side by side in a longitudinal direction of the honeycomb structure, all of the through holes being open on an end face of the honeycomb unit, and separated from each other by wall surfaces of the through holes; wherein each of the honeycomb units includes wherein the plurality of honeycomb units are formed by firing a material including the ceramic particles and the at least one of the inorganic fibers and the whiskers at a temperature of about 600° C. to about 1200° C.; wherein an area of a cross section of one of the honeycomb units perpendicular to a longitudinal direction of the one of the honeycomb units is greater than or equal to about 5 cm wherein a ratio of a sum of areas of the cross sections of the honeycomb units perpendicular to the longitudinal direction of the honeycomb units to an area of a cross section of the honeycomb structure perpendicular to the longitudinal direction of the honeycomb structure is greater than or equal to about 85%.
