PROBLEM TO BE SOLVED: To provide a scintillator plate capable of enhancing emission luminance through the enhancement of luminous efficiency due to exposure to radiation and of enhancing the sharpness (MTF). SOLUTION: In scintillator plates produced by coating and drying embrocation which scatters at least one sort chosen from oxygenation gadolinium (Gd<SB>2</SB>O<SB>3</SB>), containing activation material and oxy-sulfuration gadolinium (Gd<SB>2</SB>O<SB>2</SB>S) containing activation material as fluorescent material on a binder, the scintillator plate has a mean particle diameter of 0.1 to 0.9μm and an aspect ratio of 1.0 to 1.3 of the oxygenation gadolinium or the oxy-sulfuration gadolinium concerned.
