A radiation detection apparatus comprising a sensor panel which includes a sensor array including two-dimensionally arrayed photoelectric conversion elements. A scintillator layer is arranged on the sensor panel. A scintillator protection member covers the scintillator layer upon exposing a first side surface of the scintillator layer. A housing surrounds the scintillator layer and the sensor panel. The housing includes a sealing portion to which a side surface of the sensor panel adjacent to the first side surface and the first side surface are joined by a resin.
