摘要：PROBLEM TO BE SOLVED: To shorten manufacturing time and to improve the precision of a cavity surface shape. SOLUTION: In a manufacturing method of a laminated metallic mold, by which plural metal sheets 1 having cutting surfaces 1a cut to each prescribed shape are laminated and a prescribed shape of the cavity surface is formed with the cut surface 1a of each metal sheet 1, a process for laminating prescribed pieces of the metal sheets 1 and a process for cutting the laminated metal sheets 1 to the prescribed shape and also, welding with a laser beam, are repeatedly executed.
