Abstract
A scintillator plate provided with a scintillator having, on a substrate, a first surface facing the substrate and a second surface on an opposite side to the first surface is provided. The scintillator includes needle-like crystals each containing an alkali metal halide compound, thallium iodide, and copper and/or silver as an additive element. The additive element is contained in the second surface at a concentration of not less than 0.04 mol % and not more than 0.5 mol %, and has a higher concentration in the first surface than in the second surface. A thickness of a largest portion of each of the needle-like crystals becomes not less than one time and not more than nine times a thickness at a height of 10 μm in a direction from the first surface to the second surface.
