Abstract
A honeycomb structural body including an outermost peripheral wall, and partition walls axially defining a number of through holes inside the outermost peripheral wall. The honeycomb structural body is bent around at least one line located orthogonally to an extending direction of the through holes, wherein L1/L2.gtoreq.0.8, and R.gtoreq.100 mm, in which L1 is an axial length of a longest through hole among through holes located in an outer portion of the honeycomb structural body, L2 is an axial length of a shortest through hole among through holes located in an inner portion of the honeycomb structural body, and R is a radius of curvature of a center line of the honeycomb structural body defined by continuously connecting centroids of said outermost peripheral wall of the honeycomb structural body in respective planes orthogonal to the extending direction of the through holes thereof. The outer and inner portions of the honeycomb structural body are located outside and inside a plane, respectively, passing the center line of the honeycomb structural body and always extending in parallel to the at least one line around which the honeycomb structural body is bent.
