Honeycomb structure

Abstract

The honeycomb structure includes a plurality of cells longitudinally placed in parallel with one another with a cell wall therebetween, and a catalyst supported by the cell wall. The cell wall is formed of inorganic particles, inorganic fiber matter, and inorganic binder. Aan area of the cell wall occupied by the catalyst that is supported by a surface of the inorganic fiber matter is about 5% or less of a sum of an area of the cell wall occupied by the catalyst that is supported by a surface of the inorganic particles, the area of the cell wall occupied by the catalyst that is supported by the surface of the inorganic fiber matter, and an area of the cell wall occupied by the catalyst that is supported by a surface of the inorganic binder.
