PROBLEM TO BE SOLVED: To obtain a radiation image of satisfactory image quality, by making a more accurate correction by inhibiting incident of radiation or light to a correction pixel.SOLUTION: An imaging apparatus comprises a plurality of pixels arranged in columns and rows on a substrate, each of the plurality of pixels has a plurality of first pixels for acquiring a radiation image, and a second pixel for acquiring an offset signal, and each of the first and second pixels has a conversion element for converting radiation or light to an electric signal. The imaging apparatus includes a radiation shield or a member for shielding from light, which is disposed so as to cover the surface of the conversion element of the second pixel, the surface being opposite the substrate. The member is arranged such that its orthogonal projection overlaps at least part of the surface of the conversion element of the first pixel adjacent to a second pixel among the plurality of first pixels, the surface being opposite the substrate.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】 補正用の画素への放射線又は光入射を抑制してより正確な補正を行い良好な画質の放射線画像を得る。【解決手段】 基板の上に複数の行および複数の列を構成するように配列された複数の画素を有し、複数の画素は、放射線画像の取得のための複数の第1画素と、オフセット信号の取得のための第2画素と、を有し、複数の第1画素及び第2画素はそれぞれ放射線又は光を電気信号に変換する変換素子を含み、第2画素の変換素子の基板とは反対側の表面を覆うように配された放射線遮蔽又は遮光するための部材を含む撮像装置であって、当該部材は、その正射影が複数の第1画素のうち第2画素と隣り合う第1画素の変換素子の基板とは反対側の表面の少なくとも一部まで重なるように配置されている。【選択図】 図2
