<p>Not only is a common electrode suppressed from having a high resistance, but the common electrode is also prevented from peeling. A radiation detector 1 includes a signal readout substrate 2. The signal readout substrate 2 is constructed by arranging pixel units 4 having pixel electrodes 7 in a two-dimensional matrix form on a front surface 3a of a substrate 3. On a front surface 2a of the signal readout substrate 2, formed is a photoconductive layer 17 having crystallinity. On a front surface 17a of the photoconductive layer 17, formed is a contact assistance layer 30 having conductivity. On a front surface 30a of the contact assistance layer 30, formed is a common electrode 18. A surface area per unit region of the front surface 30a of the contact assistance layer 30 is smaller than a surface area per unit region of the front surface 17a of the photoconductive layer 17. In addition, the contact assistance layer 30 is formed so as to include the common electrode 18 and so as to be included in the front surface 17a of the photoconductive layer 17 when viewed from the front.</p> |
