Abstract
A method is provided for producing an optical member. The method includes removing a portion of a low refractive index layer, which is the outermost layer of a multilayer structure in which the low refractive index layer and a high refractive index layer are layered on each other. Non-heating processing is performed on an antireflection film that is formed to cover an optical surface of an optical base member and has the multilayer structure, through irradiation with an ultrashort pulse laser beam, so as to expose the high refractive index layer.
