RADIATION DETECTOR

摘要

[PROBLEMS] A radiation detector capable of simply mounting a semiconductor layer-carrying substrate and a light irradiating means. [MEANS OF SOLVING THE PROBLEMS] Carriers remaining in an X-ray sensitive semiconductor (14) are removed by light emitted from a flat light irradiating mechanism (28) by providing a glass substrate (11) having the X-ray sensitive semiconductor (14) for converting an incident X-ray into carriers and the light irradiating mechanism (28) provided on the side opposite to the X-ray incident side of the glass substrate (11). A translucent gel-like adhesive sheet (32) interposed between the glass substrate (11) and the light irradiating mechanism (28) and the light irradiating mechanism (28) in a flat shape enable the glass substrate (11) and the light irradiating mechanism (28) to be mounted simply. In addition, since the interposed adhesive sheet (32) is translucent, light emitted from the light irradiating mechanism (28) can be applied to the glass substrate (11) through the adhesive sheet (32) without being interrupted.
