Abstract: An object of the present invention is to provide a highly reliable scintillator panel capable of attaining an image having excellent clarity by markedly suppressing scattering of light emitted from a phosphor by a simple method to give emitted light having a necessary and sufficient intensity. Provided is a scintillator panel including a substrate and a phosphor layer containing a phosphor powder, wherein the phosphor layer has a plurality of recesses in a surface thereof, an area A of openings of the recesses is 500 to 70000 µm 2 , and a ratio D/T of a depth D of the recesses to a thickness T of the phosphor layer is 0.1 to 0.9.
