An X-ray detector comprising a scintillator layer ( 38 ) provided for each pixel and adapted for converting X radiation into light, a storage capacitor ( 15 ) for storing, as electric charge, the light converted in the scintillator layer ( 38 ), and a partition layer ( 39 ) partitioning the adjoining scintillator layers ( 38 ) provided to the respective pixels. The scintillator layer ( 38 ) contains a fluorescent material (I), the partition layer contains a second phosphor (P 2 ) having optical characteristics different from those of the fluorescent material (IP 1 ). The wavelength of the fluorescent light emitted from the second phosphor (P 2 ) includes a component which is equal to or longer than the shortest wavelength of the fluorescent light emitted from the fluorescent material (IP 1 ).
