Manufacturing method of pole pole using pole pole and its pole pole

摘要

Provided are a method for producing a pole for casting and a pole mold which does not cause distortion in the pole mold. It is assumed that the disk for electroforming having the uneven pattern on the surface includes a substrate having a flat surface having a Young's modulus of 50 GPa or more and a pattern film having a Uneven pattern having a Young's modulus of 10 GPa or less formed on the surface. The flat surface of a board | substrate and the surface which is not equipped with the uneven | corrugated pattern of a pattern film are bonded together by the adhesion layer over the whole surface, and the adhesive force of the board | substrate and a pattern film by an adhesion layer is 0.01 N / 25 mm or more, 10 N / 25 mm It is below, or it is more than 10 N / 25 mm, and shall be able to reduce adhesive force to 10 N / 25 mm or less by light irradiation or heat processing to an adhesion layer.
