Abstract
This invention provides a honeycomb catalyst having an excellent purification efficiency and a small pressure loss and can be mounted even in a limited space, the honeycomb catalyst comprising: porous partition wallshaving plural pores, which are arranged to form plural cellsallowing communication between two end faces; plugging portions being arranged to plug the cellsin one of the end faces; and catalytically active componentsloaded on surfaces of partition wallsand inner surfaces of pores, wherein many catalytically active component-loading poresthrough which a gas can pass are formed in partition walls, and a ratio of a mass (M) of the catalytically active component loaded on the surfaces of partition wallsto a mass (M) of the catalytically active componentloaded on the inner surfaces of the poresis (M):(M)=1:3 to 3:1.
