The present invention is capable of supporting a large amount of catalyst, suppresses an increase in pressure loss when collecting particles, and at the same time has a high collection capacity of particles, and is capable of efficiently regenerating and purifying harmful gases. An object of the present invention is to provide a honeycomb structure to be used, wherein the honeycomb structure of the present invention mainly comprises inorganic fibers, and is a columnar honeycomb structure having a plurality of through-holes arranged in a longitudinal direction with a wall portion interposed therebetween, The inorganic fibers constituting the honeycomb structural body are more oriented along a plane perpendicular to the direction in which the through holes are formed, compared to the plane parallel to the direction in which the through holes are formed. n n Honeycomb Structure, Particle, Inorganic Fiber, Through Hole |
