ABSTRACT:
A honeycomb structure includes an inorganic particle, inorganic binder, a honeycomb unit, a first end face, and a second end face. The honeycomb unit includes plural partition walls extending along a longitudinal direction of the honeycomb unit to define through-holes. The first end face is substantially perpendicular to the longitudinal direction and provided at a first end of the honeycomb structure. The second end face is substantially perpendicular to the longitudinal direction and provided at a second end opposite to the first end in the longitudinal direction of the honeycomb structure. First circularity of the first end face and second circularity of the second end face are about 1.5 mm to about 4.0 mm. The circularity of the first end face is different from the circularity of the second end face.
