Abstract: A radiographic image capturing device includes: a sensor substrate having one surface on which a plurality of light-receiving elements are two-dimensionally arranged; and a scintillator substrate that is arranged on the side of the light-receiving elements of the sensor substrate, wherein a region having no interface between insulating layers that differ in refractive index is formed between the scintillator substrate and incident planes of the light-receiving elements of the sensor substrate.

Abstract: A radiation image capturing device includes scan lines, signal lines, radiation detection elements and switch elements. With respect to each of the radiation detection elements, a first distance between an edge of the radiation detection element and an edge of a scan line and/or a second distance between an edge of the radiation detection element and an edge of a signal line is set within a range acceptable as a manufacturing error. The center of the range is a value which maximizes a ratio obtained by dividing the area of the radiation detection element by a first parasitic capacitance between the radiation detection element and the scan line and/or a second parasitic capacitance between the radiation detection element and the signal line.
