Abstract:
1. A radiation detector for detecting radiation, comprising: a first substrate and a signal readout substrate having a plurality of pixel electrodes arranged one-dimensionally or two-dimensionally on one main-surface side of said first substrate; a crystalline photoconductive layer formed on one main-surface side of the signal readout substrate; a conductive intermediate layer formed on one main-surface side of the crystalline photoconductive layer; and a common electrode formed on one main surface of the conductive intermediate layer, wherein a surface area per unit region of the one main surface of the conductive intermediate layer is smaller than a surface area per unit region of one main surface of the crystalline photoconductive layer, the conductive intermediate layer is formed so as to include the common electrode and so as to be included in the one main surface of the crystalline photoconductive layer when viewed from one side, and a region of the conductive intermediate layer is limited to a range broader than a region of the common electrode and narrower than a region of the one main surface of the crystalline photoconductive layer when viewed from one side.
