Abstract
An imaging panel includes a photoelectric conversion layer. The surface of the photoelectric conversion layer is partly covered with an inorganic insulating film having a first opening above the photoelectric conversion layer. An organic insulating film having a second opening having a larger opening width than the first opening is disposed on the inorganic insulating film. A surface of the inorganic insulating film that is not covered with the organic insulating film is covered with the protection film at the inside of the second opening. The etching rate of the protection film upon etching with an etchant containing an acid is equal to or higher than that of the inorganic insulating film. The surface of the photoelectric conversion layer at the first opening and the surface of the protection film are covered with an electrode.
