Abstract
The present invention provides an exhaust gas purification catalyst provided with: a substrate of wall flow structure in which inlet cells and outlet cells are partitioned by porous partition walls; and a catalyst layer disposed at least inside the partition wall and including a catalyst body. The catalyst layer satisfies the following conditions: (1) the pore volume of pores no larger than 5 μm, as measured in accordance with a mercury intrusion technique, is 24000 mmor greater per L of volume of the substrate; and (2) a permeability coefficient measured by a Perm porometer is 0.6 μmto 4.4 μm.
