PROBLEM TO BE SOLVED: To protect a base from external impact shock.SOLUTION: There is provided a portable radiation image capturing device 1 comprising a sensor substrate 51 on which a plurality of radiation detection elements 7 are arrayed in two-dimensional form, a tabular base 50 for supporting the sensor substrate, and a housing 40 in which the base is contained, the housing including a front member 41 on the side where radiation is incident and a back member 42 on the side opposite to the front member. The front member or back member includes a side wall part 416 facing the outer edge of the base, an abutment part 52 projecting from the outer edge and placed against the inside face of the side wall part is provided in the base, and a thick part 53 thicker than other portions of the base with regard to the radiation incident direction is formed between the rear end 523 and a pair of side faces 524 of the abutment part and the plain face of the base.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】基台を外部の衝撃から保護する。【解決手段】複数の放射線検出素子7が二次元状に配列されたセンサー基板51と、センサー基板を支持する板状の基台50と、基台が収納された筐体40とを備え、筐体が、放射線が入射する側のフロント部材41と、当該フロント部材とは反対側のバック部材42とを有する可搬型放射線画像撮影装置1であって、フロント部材又はバック部材は、基台の外縁部に対向する側壁部416を有し、基台には、外縁部から突出して側壁部の内側面に突き当てられる突き当て部52が設けられ、突き当て部の後端面523及び一対の側面524と基台の平面との間に、放射線入射方向について基台の他の部分よりも厚い肉厚部53が形成されている。【選択図】図5
