Abstract
An exhaust gas purifying catalyst () includes: a three-dimensional structural substrate () having a plurality of cells () partitioned by cell walls () having pores (); and catalyst layers () formed in the three-dimensional structural substrate (). The catalyst layers () have pore-cover portions () formed on surfaces () of the pores () of the cell walls (). In addition, the catalyst layers () of the pore-cover portions () have activated pores () with a pore diameter of 0.1 micrometers to 10 micrometers. In the exhaust gas purifying catalyst (), the obstruction of the vent holes (pores ()) in the catalyst layers () can be controlled, and the pressure loss can be reduced.
