Claim Text:
1. A radiation image detection device, comprising: a planar scintillator that converts radiation into visible light; a substrate that supports the scintillator; and scintillator protection film that includes a covering portion that covers a surface of the scintillator and a peripheral portion that is in close contact with the substrate around the scintillator, the covering portion and the peripheral portion being brought into close contact with the scintillator and the substrate by a planar member having a rough surface so that irregularities are formed on the surface of the covering portion and the peripheral portion, wherein the irregularities form a plurality of recesses and projections along an upper surface of a cross-section of the covering portion and the peripheral portion, the scintillator has a plurality of columnar crystals, and a distance between two of the plurality of recesses formed by the irregularities is larger than a diameter of one of the plurality of columnar crystals and is smaller than a width of the peripheral portion.
