Abstract
This scintillator plate 1 is a scintillator plate which is a member of a flat plate shape to emit scintillation light according to incidence of radiation transmitted by an object A and which is used in an image acquisition device to condense and image the scintillation light, the scintillator plate comprising: a partition plate 2 of a planar shape which transmits radiation; a scintillator 3 of a flat plate shape which is arranged on one surface 2a of the partition plate 2 and which converts the radiation into scintillation light; and a scintillator 4 of a flat plate shape which is arranged on the other surface 2b of the partition plate 2 and which converts the radiation into scintillation light.
