PROBLEM TO BE SOLVED: To obtain a porous sintered compact having a fixed pore diameter without changing the kind of a blowing agent to be added to a slurry, the concentration of the blowing agent, viscoelasticity of the slurry, particle diameter and particle shape of raw material powder contained in the slurry, a time that the foamy slurry loses fluidity by crosslinking polymerization. SOLUTION: In this method for producing the porous sintered compact comprising a process for preparing the slurry of raw material powder and an organic substance to be cured by crosslinking polymerization, a process for foaming the slurry to give a foamy slurry, a process for adding a crosslinking agent to the foamy slurry and feeding the slurry into a mold, a process for curing the foamy slurry by crosslinking polymerization to give a molding product and a process for sintering the molding product, in the process for introducing the slurry to the mold, foams are expanded or compressed by decompression or compression and the molding product is cured while maintaining the state control the pope diameter of the porous sintered compact.
