A honeycomb catalyst body (300) includes a honeycomb structure (100) that includes a porous partition wall (4) that has a number of pores and is disposed to form a plurality of cells (3) that extend between two end faces of the honeycomb structure, and a plurality of plugging sections (10) that are disposed to plug the plurality of cells (3) on either of the end faces or inside the plurality of cells (3), and a catalyst layer (15) that is supported on the surface of the partition wall (4) and contains a catalyst, the partition wall (4) having a thickness of 76.2 to 177.8 µm, an average pore size of 8 to 30 µm, and a porosity of 10 to 35%, and the honeycomb structure having a cell density of 12.4 to 45.0 cells/cm 2 . |
