ABSTRACT:
An X-ray detector consists of a substrate, a light reflecting layer, an optical fiber group, a light-shielding layer, an intensifying screen, a light-shielding member, and an optical detector. A coarse portion is formed on at least one surface of the optical fiber group, which is arranged to be substantially flat so as to correspond to a detection area. The light reflecting layer, the optical fiber group having the coarse portion, the light-shielding layer having an opening corresponding to the detection area, and the intensifying screen are disposed on the substrate in the order named. A laminated layer of the substrate, the light reflecting layer, the optical fiber group, the light-shielding layer, and the intensifying screen, excluding an extension of the optical fiber group, is covered with the light-shielding member. The distal end of the extension of the optical fiber is coupled to the optical detector.
