HONEYCOMB FILTER AND PRODUCTION METHOD FOR HONEYCOMB FILTER
A honeycomb filter of the present invention includes a ceramic honeycomb substrate having a large number of cells placed longitudinally in parallel with one another with a cell wall interposed therebetween, each of the cells passing fluid therethrough and being sealed at either a fluid inlet end or a fluid outlet end of the cell; an auxiliary filter layer formed on a surface of the cell wall of the cell opened at the fluid inlet end and sealed at the fluid outlet end in the surface of the cell wall; and an SCR catalyst supported on a surface of the cell wall of the cell sealed at the fluid inlet end and opened at the fluid outlet end, in the cell wall on which the auxiliary filter layer is formed. The honeycomb filter includes a portion that satisfies a < b, given that an average pore diameter of pores of the auxiliary filter layer is a (µm), and an average particle diameter of particles constituting the SCR catalyst is b (µm).
