Abstract
A method of turning the surface of a die, which is used to make a product, into an antireflective roughened one includes the steps of: a) producing a first roughness on the surface of the die; and b) producing a second roughness, which is smaller than the first roughness, on the surface of the die on which the first roughness has already been produced.
