Abstract

PURPOSE:To form a curved reflecting mirror having a high reflectivity without decreasing the reflectivity even in a peripheral part by continuously changing the film thicknesses in the respective film plane directions of 1st films and 2nd films and/or the mixing ratios of plural materials constituting said films and specifying the optical film thicknesses of the respective parts constant in the predetermined direction of a reflecting mirror. CONSTITUTION:The 1st film 14 consisting of a material having a low refractive index and the 2nd films 15 consisting of a material having the refractive index higher than the refractive index of the 1st films 14 are alternately laminated on the concave curved surfaces of a substrate 11. The film thickness (d) of both the 1st films 14 and the 2nd films 15 is continuously reduced nearer the peripheral part B than the central part A of the reflecting mirror of this embodiment and the optical film thickness nd in the respective parts of both the 1st films 14 and the 2nd films 15 is so set as to attain lambda/4 in the incoming direction of the light in parallel with the optical axis of the reflecting mirror. The high reflectivity is thereby obtd. over the entire surface of the reflecting mirror.
