RADIATION IMAGE DETECTION DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

There are provided a method for manufacturing a radiation image detection device, which can cover a scintillator without damaging the scintillator and which can easily form a scintillator protection film with a peripheral portion having a high adhesion to a substrate, and the radiation image detection device. A scintillator protection film that covers a planar scintillator provided on a photoelectric conversion panel is brought into close contact with a scintillator and the photoelectric conversion panel by a planar member having a surface with an irregular shape, and an irregular shape is formed on the scintillator protection film along the irregular shape of the planar member. A distance S between recesses of the irregular shape, the diameter D of the columnar crystal, and the width W of the peripheral portion satisfy the relationship of “D≦S≦W”.

主权项

1. A radiation image detection device, comprising:
a planar scintillator that converts radiation into visible light; a substrate that supports the scintillator; and a 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 surface with an irregular shape so that the irregular shape is formed on the covering portion and the peripheral portion.
