Method for producing skin material

The method for producing a skin material includes heat-pressing a raw material using an embossing die to obtain a skin material having a concave part formed on a front surface side and a flat back surface. The raw material is heat-pressed between the embossing die and an elastic mat to form, as the concave part, at least one of a plurality of concave parts for intensity display having different depths of a bottom and a concave part for gradation display in which the depth of the bottom gradually changes.
