HONEYCOMB STRUCTURE

摘要

A honeycomb structure that can carry a catalyst carrier and a catalyst without involving an increase in pressure loss, that has excellent contact with exhaust gases etc., and that can achieve a catalyst function sufficiently. The honeycomb structure is constructed by adhering porous ceramic members with adhesive layers in between, where the porous ceramic members are each composed of cells penetrating in the longitudinal direction with wall sections in between and catalyst carrier layers are adhered to the wall sections. The average diameter of the pores of the porous ceramic members is greater than the average diameter of particles forming the catalyst carrier layers. Further, when distribution of the diameters of the pores of the porous ceramic members and distribution of the particles forming the catalyst carrier layers are drawn using the same axis for the pore diameters and the particle diameters, the volume of the pores in a portion where the two are superposed is not more than 10% of the volume of the entire pores of the porous ceramic members.
