<p>A ceramic honeycomb structure (1) comprising a cell partitions (ribs) (2) forming a complex of cells (3) adjacent to one another and a honeycomb outer wall (4) encompassing and holding the outermost cells dISposed at the periphery of the cell complex. The thickness (Tc) of the basic wall (basic cell partition thickness) of each cell partition (2) is Ts≤0.12 mm. The thickness (Ts) of the honeycomb outer wall is Ts≥0.05 mm. The rate of opening area (P) of the cells is P≥80%. The thicknesses (Tr1 to Tr5-20)of the cell partitions of the cells from the outermost cell or a first start cell to a first end cell of any of the fifth to 20-th cells continuing in ward from the first start cell have a relationship with the basic cell partition thickness (Tc), 1.10 ≤ (Tr1 to Tr5-20)/Tc ≤ 3.00.</p> |
