Abstract
Provided is a radiographic imaging apparatus that is high in sharpness of a picked up image and excellent in DQE by improving the amount of light that enters a photoelectric conversion element, despite a scintillator layer being formed thick. The radiographic imaging apparatus includes: the photoelectric conversion element; and a wavelength converting layer which has a bottom surface located above the photoelectric conversion element and a top surface for receiving an incident radiation ray, and which contains a scintillator layer. The wavelength converting layer has light transmitting properties in at least a region positioned to be above the photoelectric conversion element, and contains the scintillator layer at a density that is lower on the bottom surface side than on the top surface side in the thickness direction of the region.
