Abstract

PURPOSE:To obtain the title element having high detection sensitivity by eliminating the irregularity in elements and between many elements, by forming a plurality of photodiodes composed of an amorphous photoconductive material on a scintillator substrate in an electrically independent state. CONSTITUTION:The surface forming photodiodes 4 of the substrate of a scintillator is polished so as to have a mirror surface and the photodiodes 4 are separated at every one to be formed on the substrate of the scintillator 1. Next, the scintillator 1 is cut at every element and separators 3 are held between the respective elements to separate the elements in an X-ray optical manner. As mentioned above, since the photodiodes 4 are directly formed on the scintillator 1, the positional shift between both of them is not generated and the irregularity in the elements and between them is eliminated and light transmitting efficiency is high. Further, a radiation sensor capable of performing efficient detection without generating the loss of detected X-rays and extremely easy to mount can be obtained.
