Abstract:
1. A mounting substrate on which a semiconductor light-emitting element is to be mounted, the mounting substrate comprising: a substrate that has a front surface on which the semiconductor light-emitting element is to be mounted and transmits light from the semiconductor light-emitting element; a wiring pattern on the front surface of the substrate; and a first reflective film on a back surface of the substrate, wherein the first reflective film is a multilayer film, the multilayer film includes a first film and a second film, the first film reflecting the light, which is emitted from the semiconductor light-emitting element and is transmitted through the substrate, toward the front surface of the substrate and the second film being on the first film on an opposite side to the substrate, the first film includes metal oxide microparticles that reflect the light from the semiconductor light-emitting element and a first glass frit, the second film includes a second glass frit, and a second volume concentration of the second glass frit in the second film is larger than a first volume concentration of the first glass frit in the first film.
