Abstract
A radiation detector of a compact size and producing almost no image defect is disclosed, comprising a first radiation-transmissive substrate, a first adhesive layer, a second radiation-transmissive substrate, a scintillator layer and an output substrate provided with a photoelectric conversion element layer which are provided sequentially in this order, wherein an arrangement region of the scintillator layer in a planar direction of the layer includes an arrangement region of the photoelectric conversion element layer in a planar direction of the layer and an arrangement region of the first substrate in a planar direction of the substrate, and the arrangement region of the first substrate includes the arrangement region of the photoelectric conversion element layer; and when the arrangement region of the scintillator layer is divided to plural areas, a coefficient of variation of filling factor is 20% or less which is defined as a standard deviation of filling factor of phosphor of the plural areas, divided by an average value of the filling factor.
