PROBLEM TO BE SOLVED: To provide a mechanism that realizes downsizing of a housing while suppressing a reduction in power feeding efficiency in a radiographic imaging device that is contactlessly fed with power.SOLUTION: A radiographic imaging device comprises: a radiation detector 110 for detecting an incident radiation 201 and converting it into an image signal； a detector contact conductor 120 provided in proximity to the radiation detector 110； and a power receiving coil 130 arranged together with these in the inside of a housing 150, for receiving the electric energy supplied to the radiation detector 110 contactlessly between a power feeding coil 202 arranged on the outside of the housing 150 and itself. The power receiving coil 130 is arranged in a second range 102 including a first range 101 where the detector contact conductor 120 is formed in a normal direction (direction y) relative to an incidence plane 110a upon which the radiation 201 of the radiation detector 110 is incident, in such a way that the direction of a magnetic flux Φc passing through the center of the normal direction is a planar direction (direction x) of the incidence plane 110a and a direction heading toward the radiation detector 110.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】非接触で給電を行う放射線撮影装置において、給電効率の低下を抑制しつつ筐体の小型化を実現する仕組みを提供する。【解決手段】入射した放射線２０１を検出し画像信号に変換する放射線検出器１１０と、放射線検出器１１０に接して設けられた検出器接触導電体１２０と、これらとともに筐体１５０の内部に配置され、筐体１５０の外部に配置された給電コイル２０２との間で非接触で放射線検出器１１０に供給する電気エネルギーを受電する受電コイル１３０を有し、受電コイル１３０は、放射線検出器１１０の放射線２０１が入射する入射面１１０ａに対する法線方向（ｙ方向）において検出器接触導電体１２０が形成されている第１の範囲１０１を含む第２の範囲１０２に、当該法線方向の中心を通過する磁束Φｃの向きが入射面１１０ａの面方向（ｘ方向）であって放射線検出器１１０に向かう方向となるように配置されている。【選択図】図１
