[OBJECT] To provide a radiation detector that allows a substrate with a semiconductor layer, and a light emitting device, to be attached simply. [SOLUTION] A glass substrate 11 having an X-ray sensitive semiconductor 14 for converting incident X rays into carriers, and a planar light emitting mechanism 28 disposed on a side opposite from an X-ray incidence side of the glass substrate 11 , are provided to remove carriers remaining in the X-ray sensitive semiconductor 14 by means of light emitted from the light emitting mechanism 28 . Since a gel-like adhesive sheet 32 having light transmissivity is interposed between the glass substrate 11 and light emitting mechanism 28 , and the light emitting mechanism 28 is planar, the glass substrate 11 and light emitting mechanism 28 can be attached simply. Since the adhesive sheet 32 interposed has light transmissivity, the light emitted from the light emitting mechanism 28 can be transmitted through the adhesive sheet 32 , without being blocked, to irradiate the glass substrate 11.
