Patent ID: 7728299

Claim:
A radiation image detector comprising: a photoconductive layer that generates charges by irradiation with an electromagnetic wave; and a plurality of detection electrodes for detecting signals corresponding to the charges generated in the photoconductive layer, wherein the photoconductive layer and the plurality of detection electrodes are deposited one on the other in this order, the radiation image detector further comprising: dielectrics that cover edge portions of the detection electrodes, the edge portions including the side surfaces of the detection electrodes and parts of surfaces of the detection electrodes, the surfaces continuing from the side surfaces and facing the photoconductive layer; and an anti-crystallization layer for preventing crystallization of the photoconductive layer, the anti-crystallization layer coats the dielectrics and the detection electrodes, wherein the angles of contact between the surfaces of the detection electrodes, the surfaces facing the photoconductive layer, and the dielectrics are greater than or equal to 5 degrees and less than or equal to 60 degrees.
