A honeycomb catalyst body having high mechanical strength, less pressure loss, and suitable purification performance is provided, and includes a plugged honeycomb structure having porous partition walls defining cells extending from one end face to another end face, inflow side plugged portions provided at one ends of the predetermined cells, outflow side plugged portions provided at another ends of the remaining cells, and porous projecting portions projecting so as to extend from the partition walls into the cells and being formed integrally with the partition walls; and a catalyst loaded onto the projecting portions of the plugged honeycomb structure, wherein porosities of the partition walls are 40% or more and smaller than 60%, thicknesses of the projecting portions are from 30 to 140% of thicknesses of the partition walls, and a catalyst amount loaded onto the partition walls thereof is smaller than a catalyst amount loaded onto the projecting portions.
