RADIATION IMAGING APPARATUS

A radiation imaging apparatus includes the following, a radiation detector that detects radiation; an electronic circuit; a plurality of electric wiring that connects the electronic circuit; a supporter that supports the radiation detector; and a case that includes a front surface portion in which radiation is incident and a rear surface portion facing the front surface portion with the radiation detector in between. The case stores the radiation detector, the electronic circuit, the plurality of electric wiring and the supporter. The plurality of electric wiring is positioned between the supporter and the rear surface portion, and at different positions in a thickness direction of the radiation imaging apparatus. The plurality of electric wiring include GND wiring that is used for a power supply. The GND wiring is positioned in a position farther from the radiation detector than other wiring in the thickness direction.
