The present invention provides radiographic imaging elements that can obtain a radiographic image by irradiation with radiation of different energies at a single time, while suppressing positional misalignment. Namely, radiographic imaging elements are disposed layered on one face-side of a support substrate. A signal detection circuit and a scan signal control circuit are disposed on the opposite face-side of the support substrate, these circuits performing at least one of control of detection and/or signal processing of image signals in the respective radiographic imaging elements. The signal detection circuit and the scan signal control circuit are connected to the respective radiographic imaging elements by connection lines, enabling communication.
