PROBLEM TO BE SOLVED: To provide a scintillator plate, capable of enhancing the emission luminance by making the luminous efficiency improved due to exposure to radiation and of improving the sharpness (MTF). SOLUTION: In scintillator plates, produced by coating and drying a coating liquid which scatters at least one kind chosen from among gadolinium oxide (Gd<SB>2</SB>O<SB>3</SB>) containing activation material and gadolinium oxysulphide (Gd<SB>2</SB>O<SB>2</SB>S) containing activation material as fluorescent material on a binder, the scintillator plate is such that by keeping a mean particle diameter of 0.1 to 0.9μm and an aspect ratio of 1.0 to 1.3 of the gadolinium oxide or the gadolinium oxysulphide.
