Radiation ray detector

A radiation ray detector, comprising:

• an electrode substrate comprising a transparent substrate, a plurality of thin film transistors formed on the transparent substrate, a plurality of collecting capacitors formed on the transparent substrate, an insulation layer formed on the transparent substrate including these thin film transistors and collecting capacitors, and a plurality of photoelectric conversion elements connected to respective thin film transistors and converting visible light into an electrical signal;
• a scintillator layer formed on the electrode substrate to convert radiation rays into visible light;
• and
• a protective layer comprising at least a reflective layer formed on the scintillator layer and containing a thermoplastic polymer compound and a titanium oxide powder contained therein in an amount of 70 wt % or more, a frame-shaped adhesive layer bonded to the reflective layer on the surface of the electrode substrate surface and the side wall of the scintillator, and a moisture-proof layer having a moisture transmittance of 0.5 g/m2/day or less at 40° C. and 90% RH adhered to the frame-shaped adhesive layer.
