In a cross section orthogonal to an extending direction of the cells, inflow cells have a pentagonal or a hexagonal shape, and outflow cells have a square shape. The cells are configured that the inflow cells surround one outflow cell and one side of an inflow cell and one side of an adjacent outflow cell are parallel to each other. The partition wall is configured that thickness of a first partition wall disposed between the inflow cells and the outflow cells is smaller than thickness of a second partition wall disposed between the inflow cells.

摘要： A honeycomb filter includes a honeycomb structure and plugged portions. Partition walls of the honeycomb structure are made of a partition wall material including a plurality of aggregates containing silicon carbide or silicon nitride as a main component, and a binding material at a content of 15 to 35 mass %. The binding material is made of a material in which mullite particles as reinforcing particles may be dispersed in cordierite. A thermal expansion coefficient of the partition walls at 40 to 800° C. is 4.2×10−6 1/K or less. When a value of a stress applied to the partition wall material at 900° C. is normalized by the maximum value of the stress applied to the partition wall material, a percentage of a plastic deformation displacement in a total displacement at a normalized stress value of 0.9 is in a range of 0.3 to 10%.
