PROBLEM TO BE SOLVED: To provide a radiation imaging device having a laminate structure in which an imaging element is sandwiched by a scintillator and a base, and in which the imaging element or the scintillator can be separated under a mechanically stable state of the imaging element.SOLUTION: The radiation imaging device includes a base 2, an imaging element 4, a scintillator 6, a first heat-separation type adhesive member 3 having a property of degrading of its adhesive strength by heating and for fixing the base 2 and the imaging element 4, and a second heat-separation type adhesive member 5 having an adhesive strength degrading temperature being the same as the first heat-separation type adhesive member 3 and for fixing the imaging element 4 and the scintillator 6. A heat transfer amount of the base 2 per unit time period and a heat transfer amount of the scintillator 6 per unit time period are different from each other.COPYRIGHT: (C)2012,JPO&INPIT【課題】 撮像素子をシンチレータと基台とで挟んだ積層構成からなる放射線撮像装置において、撮像素子を機械的に安定な状態で撮像素子又はシンチレータの剥離を行うことが可能な放射線撮像装置を提供する。【解決手段】 基台2と、撮像素子4と、シンチレータ6と、加熱により接着力が低下する性質を有し、基台2と撮像素子4とを固定するための第1の加熱剥離性接着部材3と、第1の加熱剥離性接着部材3と接着力が低下の温度が等しく、撮像素子4とシンチレータ6とを固定するための第2の加熱剥離性接着部材5と、を有し、基台2の単位時間当たりの熱伝達量とシンチレータ6の単位時間当たりの熱伝達量とが異なる。【選択図】 図1
