Abstract
A radiation detector includes a signal readout substrate. The signal readout substrate is constructed by arranging pixel units having pixel electrodes in a two-dimensional matrix form on a front surface of a substrate. On a front surface of the signal readout substrate, formed is a photoconductive layer having crystallinity. On a front surface of the photoconductive layer, formed is a contact assistance layer having conductivity. On a front surface of the contact assistance layer, formed is a common electrode. A surface area per unit region of the front surface of the contact assistance layer is smaller than a surface area per unit region of the front surface of the photoconductive layer. In addition, the contact assistance layer is formed so as to include the common electrode and so as to be included in the front surface of the photoconductive layer when viewed from the front.
