An X-ray detector 1 includes: an X-ray conversion layer 17 which is made of amorphous selenium and absorbs incident radiation and generates charges; a common electrode 23 provided on a surface on the side on which radiation is made incident of the X-ray conversion layer 17; and a signal readout substrate 2 on which a plurality of pixel electrodes 7 for collecting charges generated by the X-ray conversion layer 17 are arrayed, and further includes: an electric field relaxation layer 13 provided between the X-ray conversion layer 17 and the signal readout substrate 2 and containing arsenic and lithium fluoride; a crystallization suppressing layer 11 provided between the electric field relaxation layer 13 and the signal readout substrate 2 and containing arsenic; and a first thermal property enhancement layer 15 provided between the electric field relaxation layer 13 and the X-ray conversion layer 17 and containing arsenic. |
