Abstract
An antireflection film capable of reliably preventing light (or laser light), which is incident on a glass substrate and which reaches a metal film, from being reflected by the metal film. The antireflection film provided between a metal film having a complex refractive index represented by N=n−i·kand a glass substrate having a refractive index Nincludes, from the metal film side: (A) a first dielectric layer having a refractive index N; (B) a second dielectric layer provided on the first dielectric layer and having a refractive index N; and (C) a third dielectric layer provided on the second dielectric layer and having a refractive index N, in which N<n, N>N, N<N, and N>Nhold. Accordingly, light which is incident on the glass substrate and which reaches the metal film is prevented from being reflected by the metal film.
