Abstract:
1. A radiation image pickup apparatus, comprising: a conversion circuit unit in which a plurality of pixels are two-dimensionally arranged on a substrate; a readout circuit unit for reading signals from the conversion circuit unit; a bias power source for supplying a converting bias to a conversion device for converting irradiated radiation into electrical signals; and a reset power source for supplying a reset bias to the conversion device, wherein each of the pixels includes the conversion device converting incident radiation into electrical signals and having a first electrode and a second electrode, a source-follower-type first field-effect transistor outputting the electrical signals generated by the conversion device and having a gate electrode connected to the first electrode, and a second field-effect transistor for resetting the conversion device, and wherein the readout circuit unit uses an integrated circuit and is mounted on a position nearby the conversion circuit unit, the bias power source is connected commonly to the second electrode of each of the pixels, the reset power source is connected commonly to the second field-effect transistor of each of the pixels, and at least one of the bias power source and the reset power source is set in the readout circuit.
