The invention relates to a porous ceramic structural body. The development of a porous ceramic structural body which does not require any coat treatment with [gamma]-alumina, and can load a sufficient amount of catalyst for maintaining high catalyst activity without causing decrease in strength is desired. A honeycomb structure (1) is formed of a porous ceramic material and has pores (5) in the structural body, wherein cerium dioxide is present in a state that it is incorporated in the structural body in the ceramic material, and at least a part of cerium dioxide particles (6) is exposed on pore surfaces (5a) of the pores (5). The ceramic material includes cordierite or silicon carbide as a major component, the ratio of the cerium dioxide to the ceramic material is in the range of from 1.0% by mass to 10.0% by mass, and at least a part of catalyst particulates (7) of a platinum group element such as platinum or palladium is loaded by the cerium dioxide particles (6).
