PROBLEM TO BE SOLVED: To increase an impact resistance while suppressing lowering of the sensitivity of a radiation image detector.SOLUTION: Radiation image detectors (1, 2) comprise: a substrate (14) in which a recess having at least a bottom including an all radiography area is formed fluorescent bodies (18A, 18B) containing a fluorescent material emitting fluorescence by radiation exposure and provided in the recess of the substrate a group of photo-electric conversion elements (26) provided on the side opposite to the recess in which the fluorescent bodies are provided and photo-electrically converting the fluorescence emitted from the fluorescent bodies support bodies (12A, 12B) for supporting the fluorescent bodies and a fixing part (13A) for fixing the support bodies and the substrate. The photo-electric conversion elements, the substrate, the fluorescent bodies, and the support bodies are arranged in this order from a radiation incidence side.COPYRIGHT: (C)2012,JPO&INPIT【課題】放射線画像検出装置の感度低下を抑えつつ、耐衝撃性を向上させる。【解決手段】少なくとも全放射線撮影領域を含む底部を有する凹部が形成された基板(14)と、放射線露光によって蛍光を発する蛍光物質を含有し、前記基板の凹部に設けられる蛍光体(18A、18B)と、前記蛍光体が設けられた凹部とは反対側に設けられ、前記蛍光体から発せられた蛍光を光電変換する光電変換素子の群(26)と、前記蛍光体を支持する支持体(12A,12B)と、前記支持体と前記基板とを固定する固定部(13A)と、を備え、放射線入射側から、光電変換素子、基板、蛍光体、支持体の順に並んでいる放射線画像検出装置(1,2)。【選択図】図1
