PROBLEM TO BE SOLVED: To provide a radiographic imaging apparatus capable of easily suppressing an impact of reflection of a radiographic imaging apparatus behind it on a captured image when performing one-shot long-sized imaging.SOLUTION: A radiographic imaging apparatus 1 includes a sensor panel SP in which a plurality of radiation detection elements are arranged in a two-dimensional fashion, and a housing 40 in which the sensor panel is accommodated, the housing having a front plate 41 on a radiation incident side, a back plate 42, and side wall parts 41B and 41C. The side wall part 41B includes a projecting strip part 45 along the height direction of the side wall part, which projects from an inner side wall surface of the side wall part, and a height change part 46 in which the height in the height direction gradually changes is formed in the lateral parts on both sides in the longitudinal direction of the side wall part of the projecting strip part.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】1ショット長尺撮影を行う場合に、後方の放射線画像撮影装置の映り込みに対して撮像画像への影響を容易に抑えることが可能な放射線画像撮影装置を提供する。【解決手段】複数の放射線検出素子が二次元状に配列されたセンサーパネルSPと、センサーパネルが収納された筐体40とを備え、筐体が、放射線が入射する側のフロント板41と、バック板42と、側壁部41B,41Cとを有する放射線画像撮影装置1において、側壁部41Bは、側壁部の内側壁面から突出し、当該側壁部の高さ方向に沿った凸条部45を有し、凸条部における側壁部の長手方向の両側の側面部に、高さ方向の高さが徐変する高さ変化部46が形成されている。【選択図】図3
