    摘要： A honeycomb filter includes a pillar-shaped honeycomb fired body having a large number of cells each sealed at either end thereof and placed longitudinally in parallel with one another with a cell wall therebetween. A sum of cross-sectional areas perpendicular to a longitudinal direction of cells having openings on a gas inlet side is about 1.5 to about 3.0 times larger than a sum of cross-sectional areas of cells having openings on a gas outlet side. A catalyst supporting layer is formed in a catalyst-supporting-layer area covering about 25 to about 90% of an overall length of the honeycomb filter, and substantially no catalyst supporting layer is formed in a non-catalyst-supporting-layer area covering about 10% of the overall length of the honeycomb filter. The non-catalyst-supporting-layer area abuts the gas outlet side. A thermal conductivity of the non-catalyst-supporting-layer area is higher than a thermal conductivity of the catalyst-supporting-layer area.

    摘要： The present invention provides a method for producing a honeycomb structure which carries a catalyst component containing at least one element selected from the group consisting of alkali metals and alkaline earth metals and purifies exhaust emissions. The method of the invention includes: a starting material mixing step of mixing ceramic particles having a predetermined average particle size, fine particles being composed of the same material as the ceramic particles and having an average particle size smaller than the predetermined average particle size, and an erosion-resistant material or a precursor thereof which inhibits the catalyst component from eroding the ceramic particles more effectively than an oxide of the element contained in the ceramic particles, to prepare a puddle; a molding and firing step of molding the puddle into a molded body and firing the molded body to sinter the molded body and to allow a ceramic particle protection material composed of the erosion-resistant material or the precursor thereof to be present on the surface of the molded body; and a catalyst-carrying step of making the fired molded body to carry the catalyst component.
