Abstract

To enable fabrication of a precise stamped product having an extremely low surface roughness. Rippleshaving depths ranging from 10 to 100 nm are formed with periodicities ranging from 100 to 1000 nm on a stamping tool surface that comes into contact with a workpiece material. The rippleshave a stripe shape extending in a direction substantially perpendicular to the direction of sliding between the stamping tool (die) and the workpiece material (the direction of the arrow a). The ripplesserve as micro pools. For example, a product that is required to have a surface roughness of the order of several tens of nm or lower can be satisfactorily stamped.
