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.
