There are provided a scintillator panel excellent in productivity and exhibiting enhanced emission-extracting efficiency and sharpness, resulting in reduced deterioration in sharpness between planar light-receiving element, and a radiation flat panel detector. The scintillator panel comprises a scintillator plate, wherein the scintillator plate comprises a protective layer comprising the first protective film provided on the side of the scintillator layer and the second protective film provided on the side of the substrate opposite the scintillator layer and the protective layer has a lug which is a sealed portion of the first protective film and the second protective film, and the length of the lug of the protective layer is represented by a specific expression, the first protective film is not adhered to the scintillator layer and the scintillator plate is provided as a constituent element for a radiation flat panel detector without being physicochemically adhered to the surface of a planar light receiving element.
