Abstract
A scintillator includes a plurality of columnar crystals. A surface protection film is made of poly-para-xylyene and covers a surface of the scintillator, and the front ends of the columnar crystals penetrate thereinto. A photoelectric conversion panel includes a glass substrate and an element unit formed on the glass substrate. The element unit includes a plurality of pixels, is disposed opposite to the front ends of the columnar crystals, and detects visible light which is emitted from the front ends and is transmitted through the surface protection film in a light receiving region of each pixel so as to be converted into electric charge. To improve an SN ratio, a penetration amount P of the front end into the surface protection film and an area A of the light receiving region of each pixel are set to satisfy a relationship of 0 m<P/A≦1.4×10m.
