Honeycomb structure
A honeycomb structure includes a honeycomb body having a partition wall defining a plurality of cells that extend from an inflow-end face as one end face to an outflow-end face as the other end face, the honeycomb body having a circumferential shape at a cross section orthogonal to an extending direction of the cells that is a rectangular shape with four corners being chamfered and having a long diameter and a short diameter, wherein the plurality of cells are hexagon cells having a hexagonal shape at the cross section orthogonal to the extending direction of the cells, and the hexagon cells are configured so that a longest diagonal line of each hexagon cell and the long diameter L of the honeycomb body form an angle that is 0 to 6°.
