An X-ray image detector system includes: a plurality of scanning lines; a plurality of signal lines formed so as to intersect the scanning lines; and a plurality of pixel parts, each of which is formed at a corresponding one of the intersections between the scanning lines and the signal lines so as to form an array; each of said pixel parts having an X-ray-to-charge converting part for converting an incident X-ray to an electric charge, a pixel electrode for receiving the electric charge from the X-ray-to-charge converting part, and a switching element which is operated on the basis of a signal of a corresponding one of the scanning lines, one end of the switching element being connected to the pixel electrode, and the other end of the switching element being connected to a corresponding one of the signal lines, wherein the X-ray-to-charge converting part includes at least a first X-ray-to-charge converting film, and a second X-ray-to-charge converting film having a lower resistivity than that of the first X-ray-to-charge converting film. Thus, it is possible to provide an X-ray image detector system capable of detecting an image even if X-ray irradiation is weak.
