This radiation detector is provided with: a sensor board including a flexible substrate, and a layer which is provided on a first surface of the substrate and in which are formed a plurality of pixels which accumulate charge generated in accordance with light converted from radiation； a converting layer which is provided on the side of the layer in which the pixels are formed that is on the opposite side to the side on which the substrate is provided, and which converts radiation into light； and a stress neutral plane adjusting member which is provided on a second surface side on the substrate, on the opposite side to the first surface, and which adjusts the position of a stress neutral plane to be within a pre-determined range from an interface, which is the surface of the converting layer opposing the sensor board, in a stacking direction P in which the sensor board and the converting layer are stacked.提供一種放射線檢測器以及放射線圖像拍攝裝置。放射線檢測器具備：感測器基板，其包含撓性的基材、以及設置於基材的第1面且形成有蓄積對應於從放射線變換的光而產生的電荷的多個像素的層；變換層，其設置於形成像素的層中的設置基材的一側的相反側，將放射線變換成光；和應力中立面調整構件，其設置於基材的第1面的相反側的第2面側，將應力中立面的位置從與感測器基板對向的變換層的面即界面調整到感測器基板以及變換層層疊的層疊方向P的預先確定的範圍內。
