To provide a radiation detector that can protect electronic components from impacts generated when the detector falls down.SOLUTION: The radiation detector includes: a radiation detection panel 2； a supporting member provided with a radiation detection panel 2 on a first surface side； an electronic component 18 located on a second surface side of the supporting member； and a housing 5 for containing the radiation detection panel 2, the supporting member, and the electronic component 18. A bottom 15 of the housing 15 facing the second surface of the supporting member includes: a flat part 20； and a slope part 21 adjacent to the flat part 20 and closer to the second surface of the supporting member in a position closer to the opposite side to the flat part 20. The electronic component 18 is arranged in a position where at least the center O of the gravity of the electronic component 18 overlaps with the slope part 21.SELECTED DRAWING: Figure 3【課題】倒れた際に加わる衝撃から電子部品を保護できる放射線検出装置を提供する。【解決手段】放射線検出装置は、放射線検出パネル２と、放射線検出パネル２が第１面側に配置される支持部材と、支持部材の第２面に配置される電子部品１８と、放射線検出パネル２と、支持部材と、電子部品１８とを収容する筐体５を、備え、支持部材の第２面に対向する筐体５の底１５は、平坦部２０と、平坦部２０に隣接されており且つ平坦部２０とは反対側ほど支持部材の第２面に近接しているスロープ部２１と、を有し、電子部品１８は、少なくとも電子部品１８の重心Ｏがスロープ部２１に重なる位置に配置されている。【選択図】図３
