Abstract: There is disclosed a honeycomb catalyst body including porous partition walls in which a plurality of cells that become through channels of a fluid are defined and formed, and a plurality of pores are formed, wherein a cell density is from 93 to 186 cells/cm2, and onto the partition walls, a catalyst containing the zeolite is loaded in an amount of 100 to 300 g/L, a porosity (A) of the partition walls before the catalyst is loaded thereonto is 50% or more, and a porosity (B) of the partition walls in a state where the catalyst is loaded thereonto is from 0.3 to 0.6 times as much as the porosity (A).
