Abstract

There is disclosed a honeycomb structure which can suitably remove a particulate matter in an exhaust gas discharged from a direct-injection gasoline engine and which can maintain a suitable collecting efficiency of the particulate matter for a long period of time. A honeycomb structure 100 includes porous partition walls 5 arranged to partition a plurality of cells 4 which extend through the structure from an inflow end surface 2 as the end surface on a fluid inflow side to an outflow end surface 3 as the end surface on a fluid outflow side to become through channels of the fluid and in which a shape of outer peripheral edges of open frontal areas in the inflow end surface 2 is a quadrangular shape; and plugged cells 4a as the cells 4 which are provided with plugged portions 8 at ends thereof on the side of the inflow end surface 2 and flow-through cells 4b as the cells 4 which are not provided with the plugged portions 8. Among the cells 4 adjacent to each of the flow-through cells 4b via the partition walls 5, the plugged cells 4a are two or less cells.
