Abstract
A light-emitting device according to one embodiment includes: a substrate; a graphite thin film disposed on the substrate; and an electrode provided on a second surface of the graphite thin film on an edge portion of the graphite thin film, the second surface of the graphite thin film being opposite from a first surface of the graphite thin film, the first surface of the graphite thin film opposed to the substrate. A plurality of protrusions for supporting the graphite thin film is formed on a surface of the substrate opposed to the graphite thin film, at least over an entire region where the substrate and a portion of the graphite thin film other than the edge portion overlap each other when viewed along a thickness direction of the substrate.
