PROBLEM TO BE SOLVED: To make it possible to deal with the higher performance and lighter weight of mechanical devices by constituting the porous metallic body of perfo rated metallic sintered compact skeleton having specific porosity, thereby forming the porous metallic body having the specific surface area over the entire part and the porosity over the entire part. SOLUTION: The porous metallic body is composed of the skeleton of the perforated metallic sintered compact having the porosity of 10 to 55%. The porous metallic body is so formed as to have the specific surface area over the entire part of 300 to 3000cm<2> /cm<3> and the porosity over the entire part of 80 to 97%. The formation thereof is executed by molding a molding of a mixture composed of 0.5 to 10% of a 5 to 8C non-water-soluble hydrocarbon solvent 0.05 to 5% surfactant, 0.5 to 20% water-soluble resin binder, 30 to 80% metallic powder having 0.5 to 200μm average grain size and polyhydric alcohol, etc., then sintering the molded porous molding. As a result, the higher output of various kinds of the mechanical devices is attained.
