Inorganic film and laminate
First Claim
1. An inorganic film comprising a refractive index gradient film A being composed of an inorganic material, having a refractive index changing continuously from n1 to n2 from one surface toward the other surface, and wherein n1<
- n2 and being a functional film; and
a refractive index gradient film B being composed of an inorganic material, having a refractive index changing continuously from n3 to n4 from one surface toward the other surface, and wherein n4<
n3 and being a functional film;
the refractive index gradient film B being laminated on a surface of the refractive index gradient film A on a side where the refractive index is n2 with a surface side where the refractive index is n3 being in direct or indirect contact with the surface of the refractive index gradient film A;
a difference between n2 and n3 being 0.1 or less;
the inorganic material being a complex oxide comprising Zn, Sn, and at least one of Si and Al.

Abstract
There are provided an inorganic film in which the light transmittance is not decreased also when the inorganic film is laminated on organic material such as a resin, and a laminate. An inorganic film 13 which comprises a refractive index gradient film 13a having a refractive index changing continuously from n1 to n2 (n1<n2) and being a functional film; and a refractive index gradient film 13b having a refractive index changing continuously from n3 to n4 (n4<n3) and being a functional film, and in which further, a difference between n2 and n3 is 0.1 or less.
