DETECTION DEVICE AND DETECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a detection device capable of achieving both of good adhesion between an impurity semiconductor layer and a pixel electrode and good dark current characteristics of a conversion element.SOLUTION: In a detection device having a substrate 100 capable of transmitting visible light; a conversion element 12 which has a pixel electrode, an impurity semiconductor layer 123 and a semiconductor layer 124 in order from the substrate 100 side and converts radioactive ray or light into electrical charge; and a light source 24 which irradiate the conversion element 12 with visible light through the substrate 100, the pixel electrode contains a metal layer 122 having a thickness in which at least part of it can transmit visible light.
