Abstract
A folding mirror includes a substrate and a dielectric multilayered film formed on a surface of the substrate. The dielectric multilayered film includes a first period layer with a structure represented by a formula (0.58H1.16L0.58H), a second period layer with a structure represented by a formula (0.8L1.6H0.8L), and a third period layer with a structure represented by a formula (0.95L1.9H0.95L), wherein, H represents a thickness of a high refractive index layer being set at ¼ of a reference wavelength associated with the film, and L represents a thickness of a low refractive index layer being set at ¼ of a reference wavelength associated with the film, all of the N1, N2, and N3 represent the numbers of repetitions of the structures, enclosed by the corresponding parentheses, forming the first period layer, the second period layer, and the third period layer respectively.
