摘要： A honeycomb structure includes a pillar-shaped honeycomb structure body including porous partition walls defining and forming a plurality of cells which extend from an inflow end face to an outflow end face, and a porous outer wall surrounding the partition walls, a porous supporting bulge disposed to extend out from a circumference of the outer wall so that at least a part of the outer wall is exposed, and plugging portions arranged in open ends of the cells, and the supporting bulge has support portions and a side wall portion, and the partition walls and the outer wall of the honeycomb structure body and the support portions and the side wall portion of the supporting bulge are all formed monolithically by formation of a ceramic raw material.

摘要： A honeycomb filter, including: a honeycomb structure, wherein the honeycomb structure further includes a platinum group element-containing catalyst layer and a trapping layer, the platinum group element-containing catalyst layer is disposed at least on an entire surface of a side of an inner surface of the partition walls surrounding either one of the inflow cells or the outflow cells, the trapping layer does not contain a platinum group element, and the trapping layer is disposed in a range of at least up to 50% with respect to an overall length of the honeycomb structure starting from the outflow end face and is not disposed in a range of at least up to 40% with respect to the overall length starting from the inflow end face, in an extending direction of the cells of the honeycomb structure.

摘要： A pillar shaped honeycomb structure, including: a porous partition wall that define a plurality of cells, the plurality of cells forming flow paths for a fluid, the plurality of cells extending from an inflow end face to an outflow end face; and an outer peripheral wall located at the outermost circumference. The plurality of cells include: a plurality of first cells; and a plurality of second cells having a lower cross-sectional area than that of the plurality of first cells. An interior of each of the second cells is filled with a material comprising a magnetic substance. Each of the second cells are arranged adjacent to at least one of the first cells.

摘要： A honeycomb catalyst body includes a tubular honeycomb base material having porous partition walls to define and form a plurality of cells extending as through channels of a fluid from one end surface from which the fluid flows in to the other end surface from which the fluid flows out, and a catalyst loaded onto the partition walls. In the honeycomb base material, at least one slit which is open in a side surface of the honeycomb base material is formed, and a width of the slit is from 1.0 to 10.0 mm.
