A honeycomb catalyst body includes a modified honeycomb structure that includes a porous partition wall having a number of pores,, and a catalyst that is supported in a given area of the partition wall. The modified honeycomb structure includes a first area that includes a modified partition wall and includes at least part of one end face, a number of particles adhering to an inner surface of pores formed in the modified partition wall, and a second area that includes an unmodified partition wall and includes at least part of the other end face, the particles not adhering to the unmodified partition wall, the modified partition wall having a porosity lower than that of the unmodified partition wall, and an amount of the catalyst supported in the first area per unit volume being smaller than that of the second area. |
