The honeycomb structure body has a cell density distribution in which a cell density is reduced continuously or stepwise from a center portion to an outer peripheral portion in a radial direction. The honeycomb structure body has wave shaped cell walls and flat shaped cell walls which extend in an axial direction. Particularly, the wave shaped cell walls are formed in a formation section having a cell density ratio of not more than 0.85 to a maximum cell density.
