Abstract
A radiographic apparatus is provided which is capable of converting an X-ray directly into an electric signal, high in resolution and detection efficiency, and easy to manufacture. On at least one surface of a compound semiconductor substrate for generating an electric charge by X-ray irradiation, a plurality of split electrodes are disposed, and electrodes are disposed on picture elements formed on a CCD corresponding to these split electrodes, and are electrically connected to CdTe as compound semiconductor substrate and the CCD. An electric current issued from the split electrodes is divided, and is partly discharged through grounding wires.
