摘要： A honeycomb filter includes a pillar-shaped honeycomb substrate including a porous partition wall that defines a plurality of cells extending from an inflow end face to an outflow end face, an inflow side plugging portion disposed at the inflow end face of the honeycomb substrate to plug open ends of outflow cells and an outflow side plugging portion disposed at the outflow end face of the honeycomb substrate to plug open ends of inflow cells other than the outflow cells. The honeycomb substrate includes the partition wall that defines two of the inflow cells by division. An average of the plugging length LIN of the inflow side plugging portions disposed in the outflow cells of the honeycomb substrate is larger than an average of the plugging length LOUT of the outflow side plugging portions disposed in the inflow cells of the honeycomb substrate.

摘要： Provided is a honeycomb filter, including: a pillar-shaped honeycomb substrate having an inflow end face and an outflow end face and including a porous partition wall surrounding a plurality of cells; and a plugging portion disposed at any one of ends of the cells at the inflow end face and at the outflow end face. 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 larger than thickness of a second partition wall disposed between the inflow cells.

摘要： A plugged honeycomb structure includes a plurality of honeycomb segments, a bonding layer, and plugging portions plugging open ends of cells of the honeycomb segments. The honeycomb segments include circumferential segments and central segments. The circumferential segments include at least one specific circumferential segment in which pressure loss with soot when an amount of the deposited soot is 4 g/L is higher than the pressure loss with soot of the central segment as much as 15% or more and in which an open frontal area of the circumferential segment is the same as or larger than an open frontal area of the central segment. In a cross section of a honeycomb structure body which is perpendicular to an extending direction of the cells, a ratio of an area of the specific circumferential segment is 4% or more to a total area of the circumferential segments and the central segments.
