Patent ID: 8119970

Claim:
A radiation image detection apparatus, comprising a radiation image detector that includes the following stacked in the order listed below: a bias electrode to which a bias voltage is applied; a photoconductive layer that generates electric charges by receiving a recording electromagnetic wave representing a radiation image; a substrate side charge transport layer that transports the electric charges generated in the photoconductive layer; and an active matrix substrate having multiple charge collecting electrodes disposed thereon for collecting the electric charges generated in the photoconductive layer, wherein the radiation image detector does not include an area adjacent to the interface between the substrate side charge transport layer and photoconductive layer having an oxygen or chlorine element density not less than two times the average density thereof in the substrate side charge transport layer; wherein the apparatus further comprises a bias electrode side charge transport layer between the bias electrode and photoconductive layer; and wherein the bias electrode side charge transport layer includes an area having an oxygen element density not less than three times the average density thereof in the bias electrode side charge transport layer.
