摘要：
A radiation image pickup apparatus or the like which realizes improvement of noise resistance characteristics when adding pixel signals is provided. For this purpose, the radiation image pickup apparatus has a switching unit which is arranged between a signal wiring and an amplifier and can switch electrical connection among a plurality of signal wirings and electrical connection between a predetermined one of the plurality of signal wirings and the amplifier corresponding thereto. In accordance with mode setting, the switching unit switches a first state where the plurality of signal wirings are electrically connected and the predetermined signal wiring and the corresponding amplifier are electrically disconnected and a second state where the plurality of signal wirings are electrically disconnected and the predetermined signal wiring and the corresponding amplifier are electrically connected.
