RADIATION DETECTOR

To prevent deterioration of image quality so as to improve accuracy in detecting irradiation of an X-ray by effectively suppressing a vibration while keeping light-weight in a radiation detector.SOLUTION: A radiation detector 100 comprises: a radiation detection section 2 including a flexible substrate 21 and a semiconductor element 23 formed on an imaging surface 22 of the substrate; a support member 4 for supporting the radiation detection section; a housing (front surface part 1, rear surface part 8) for storing the radiation detection section; and buffer members C11-C13, C21-C23, C31-C33. The buffer members are provided at least between the support member and the radiation detection section or between the support member and the rear surface part 8.SELECTED DRAWING: Figure 1 【課題】放射線検出器の軽量性を保ちつつ、効果的に振動を抑制することで、画像品質の劣化を防ぎ、Ｘ線の照射の検出精度を向上する。【解決手段】放射線検出器１００は、可撓性を有する基板２１と、基板の撮像面２２に形成された半導体素子２３と、を有する放射線検出部２と、放射線検出部を支持する支持部材４と、放射線検出部を収容する筐体（前面部１, 背面部８）と、緩衝部材Ｃ１１－Ｃ１３，Ｃ２１－Ｃ２３，Ｃ３１－Ｃ３３とを備える。緩衝部材は、支持部材と放射線検出部との間、又は支持部材と背面部８との間の少なくとも一方に設けられる。【選択図】図１
