Abstract:
A dielectric film is provided on a transparent substrate. The dielectric film has at least one low refractive index layer. An uppermost layer of the dielectric film contains SiO2 and has a film density of 92% or more. The uppermost layer contains an element having an electronegativity smaller than Si.
