The present invention relates to a radiation imaging apparatus which increases shock resistance of an electrically conductive member for reducing radiation noise. The radiation imaging apparatus comprises: a housing including an incident surface of radiation； an imaging panel stored in the housing and including an effective region for detecting radiation incident through the incident surface； a buffer member arranged between the incident surface and the imaging panel； and an electrically conductive member fixed to the buffer member. An edge of the electrically conductive member surrounds an edge of the effective region in a planar view with respect to the incident surface.방사선 촬상 장치는, 방사선의 입사면을 포함하는 하우징과； 입사면을 통해서 입사한 방사선을 검출하는 유효 영역을 포함하고, 하우징에 격납된 촬상 패널과； 입사면과 촬상 패널 사이에 배치된 완충 부재와； 완충 부재에 고정된 도전 부재를 포함한다. 입사면에 대한 평면 뷰에 있어서, 도전 부재의 에지가 유효 영역의 에지를 둘러싼다.
