ABSTRACT:
Forming an optical element curved surface mirror with a low surface roughness and high shape precision at a low cost by only forming without employing any one of various types of polishing operations during a manufacturing process. The present invention provides an optical element processing method of forming an optical element by forming a metal base material with a die, and includes a film formation step of forming a metal film on a surface of the metal base material by PVD, CVD, plating, or dipping, and a forming step of forming the metal base material, having the metal film formed on its surface, with the die.
