Abstract
Provided is a radiation detection element, including: a plurality of electrode portions on a surface of a substrate; and an insulating portion between the electrode portions, the substrate being made of a compound semiconductor crystal containing cadmium telluride or cadmium zinc telluride, wherein an intermediate layer containing tellurium oxide is present between each of the electrode portions and the substrate, and wherein the tellurium oxide layer has a thickness of 100 nm or less on a 500 nm inner side from an end portion of the insulating portion between the electrode portions. The radiation detection element has higher adhesion of the electrodes, and does not result in an element performance defect caused by insufficient insulation between the electrodes, even if the radiation detection element has a narrower distance between the electrode portions in order to obtain a high-definition radiographic image.
