PROBLEM TO BE SOLVED: To provide a method for producing a die for press with which the parts for three-dimensional die for press having high hardness, fine surface roughness after finish-working, precise dimension, conventionally needing the skillfulness, can be formed and worked at a time. SOLUTION: This three-dimensional die 3 for press is formed and worked, by laminating a fixed amount of super hardened metallic powder 1 on a base board A, and melting and sintering the super hardened metallic powder laminated at the fixed amount, and further, laminating the metallic powder by the fixed amount on the melted and sintered metallic powder, and repeating the lamination of the metallic powder by the fixed amount, and the melting and the sintering of the powder in order.
