To provide a method for manufacturing a die having desirable transferred shape while considering the deformation developed during forging.

When a bevel gear is forged, the deforming amount given on the forming surface in the die for forging is obtained in a plurality of positions along at least any one direction of a tooth-trace direction or a tooth-width direction with a simulation and/or an experiment, and after setting a correction amount offsetting the obtained deforming amount, based on the correction amount, the criteria setting dimension in the die for forging is corrected.
