An objective is to provide a flat panel detector exhibiting high durability and less noise, which is fitted with a scintillator for radiation exhibiting high emission efficiency, wherein the scintillator is easy to be manufactured because of the simple structure. Also disclosed is a scintillator panel for radiation possessing a radiotransparent substrate and provided thereon, a phosphor layer from which light is emitted by exposing the substrate to radiation and a reflective film at which light from the phosphor layer is reflected, wherein the reflective film provided between the substrate and the phosphor layer possesses a multilayer film composed of at least two dielectric layers exhibiting a high reflectivity.
