RADIATION DETECTOR AND METHOD OF PRODUCING THE SAME

摘要

A solid-state imaging element 2 having a light-receiving portion where a plurality of photoelectric conversion elements 21 are arranged, and electrode pads 22 electrically connected to the photoelectric conversion elements 21 is mounted on a substrate 1. A scintillator 3 is formed on the surface of the light-receiving portion of the solid-state imaging element. Around a support surface wherein the solid-state imaging element 2 of the substrate 1 is mounted, positioning portions 14 to 16 are formed, which project higher than the support surface and position the solid-state imaging element 2 with side walls. The top surfaces of these positioning portions are formed such that a light-receiving surface 2a of the solid-state imaging element 2 is higher than the top surfaces. <IMAGE>
