摘要： A method of manufacturing a radiation imaging apparatus includes electrically connecting a first surface of a flexible insulating layer to a conductive portion of a circuit substrate, covering an exposed portion of the conductive portion with a protection layer, and separating the flexible insulating layer from a substrate in contact with a second surface of the flexible insulating layer. The circuit substrate includes an integrated circuit mounted on the circuit substrate. The flexible insulating layer includes, on the first surface, a plurality of pixels arranged in a two-dimensional matrix to convert radiation into an electrical signal. The second surface of the flexible insulating layer is opposite to the first surface of the flexible insulating layer. The flexible insulating layer is separated from the substrate by irradiating the second surface with light transmitting through the substrate.

The readout unit includes a reset unit that resets a potential of the signal line. A period during which the readout unit reads out a signal on the signal line includes a first period during which the signal line is reset, and a signal on the signal line in a state that the switch is not turned on is read out, and a second period during which the signal line is reset, and a signal on the signal line due to the switch being turned on is read out. The processing unit calculates a difference between the signals read out in the second and first periods.
