An aim of the present invention is to provide a technology to inhibit degradation phenomena of TFTs in an imaging panel having such TFTs in each pixel. The imaging panel captures scintillation light, which are X-rays that have passed through a specimen and been converted by a scintillator. The imaging panel includes a plurality of gate lines and a plurality of data lines. The imaging panel includes a conversion element that converts scintillation light to electric charge, a thin film transistor connected to the gate line, data line, and conversion element, and a metal wiring line connecting to the conversion element and supplying a bias voltage to the conversion element. The metal wiring line is positioned approximately parallel to the data line so as to overlap the top of the thin film transistor.
