摘要： A radiographic image capturing apparatus includes a photodetector substrate, a scintillator, a switching filter, and a resetting light source, which are arranged successively in this order. If the switching filter is made permeable to resetting light from the resetting light source, the switching filter allows resetting light to be applied to the photodetector substrate through the scintillator, whereas, if the switching filter is made impermeable to the resetting light, the switching filter reflects at least a fluorescence, which is converted from radiation by the scintillator, toward the photodetector substrate.
