Abstract: A laminated substrate for an electrochromic dimmer element includes
a glass substrate; and
a transparent conductive film.
The glass substrate includes a silicon oxide, an aluminum oxide, a boron oxide, an alkaline earth metal oxide, and an alkali metal oxide in a total amount of 90 mol % or more, and includes the alkali metal oxide in a total amount of 12 mol % or less.
The transparent conductive film includes an indium oxide film containing tin, and a tin oxide film containing at least one of tantalum, antimony and fluorine, in this order from a glass substrate side.
The indium oxide film is formed directly on the glass substrate, a refractive index and an extinction coefficient of the indium oxide film at a wavelength of 1.3 μm is less than 0.4, and greater than 0.4, respectively.
A film thickness of the tin oxide film is greater than 35 nm.

Abstract: A substrate with conductive film includes a base material; and a film of a conductive metal oxide arranged on an upper part of the base material. The film includes, by a top plan view, a first region and a second region, the second region is configured of a same material as the first region, and an electric resistance of the second region is higher than an electric resistance of the first region. The second region includes a part configured by a plurality of cellular sections surrounded by a plurality of fine cracks. In the part, each fine crack has a width of 1 nm to 50 nm, and each cellular section has a largest measure of less than 10 μm.
