Beschreibung
Zusammenfassung:	An exhaust gas purification catalyst having a substrate having a wall flow structure, and a catalyst layer. The catalyst layer has: an A section provided in the interior of the partition wall, along an extension direction X of the partition wall, from an exhaust gas inflow end section; a C section provided in the interior of the partition wall, along the extension direction X of the partition wall, from an exhaust gas outflow end section; and a B section disposed between the A section and the C section in the extension direction X of the partition wall, and provided over the surface of the partition wall on the side in contact with the inlet cell, the interior of the partition wall, and the surface of the partition wall on the side in contact with the outlet cell.
