  • Patent number: 11073624
    Abstract: A radiographic imaging apparatus, includes: a planar-shaped flexible scintillator board that emits light at an intensity according to a radiation dose of received radiation; a flexible photoelectric conversion panel that includes a plurality of photodetection elements formed so as to be distributed two-dimensionally on a surface of a flexible support board, and is arranged such that an element-formed surface on which the photodetection elements are formed faces the scintillator board, the photodetection elements generating charges according to an intensity of the received radiation; and a moisture barrier layer that is formed of a material having characteristics of preventing moisture from passing therethrough, and covers a surface of the scintillator board opposite to a surface facing the photodetection elements, a side surface of the scintillator board, and a surface of the photoelectric conversion panel opposite to the element-formed surface.
