PROBLEM TO BE SOLVED: To improve the strength of a formed material, related to a production of the metal-made formed material by using a laminated-forming method. SOLUTION: A method for producing metal-made formed material comprises: a step of forming a laminated-forming body 20 through a laminated forming treatment by using metallic powder as a forming material 2; and an infiltrating treatment step wherein an infiltrating material 23 is infiltrated into the laminated forming body 20 or a sintered material 22 obtained by applying sintering treatment to the laminated forming body 20. Then, as the filtrating material, the same alloy as the forming material is used in which a chemical potential of at least one component metal to the alloy is made larger than the chemical potential to the forming material metal.
