Transparent substrate with film and top plate for a cooking appliance
By setting a light-absorbing film composed of Ag, Al and Fe on a transparent substrate, combined with a dielectric multilayer film, the problems of unclear information display when the light source is on and poor aesthetics when the light source is off in the cooker top plate are solved, achieving stable information display and aesthetics in high-temperature environments.

Abstract
Provided is a transparent substrate with a film, which is less likely to change in optical properties due to heating and is excellent in appearance when a light source is turned off. The transparent substrate with a film (1) has a transparent substrate (2) and a light-absorbing film (3) provided on one main surface (2a) of the transparent substrate (2), the light-absorbing film (3) containing Ag, Al, and Fe at a molar ratio of Ag:Al:Fe=x:y:z (where x+y+z=1, 0
