A 2-dimensional radiation image detector wherein a plurality of conversion elements for converting a radiation into visible light and a plurality of photo-sensitive elements for detecting the visible light and accumulating signals are formed an elements board includes two elements boards arranged in an overlapping relationship with each other and each having the plurality of photo-sensitive elements arranged two-dimensionally thereon such that the distance between centers of the photo-sensitive elements in one direction of the arrangement is substantially equal to a width of the photo-sensitive elements while the distance between the centers of the photo-sensitive elements in a direction perpendicular to the one direction is substantially equal to twice the width of the photo-sensitive elements and such that that portion of a radiation directed upon the two overlapping elements boards which has passed through a first one of the elements boards other than locations of the photo-sensitive elements is detected by the photo-sensitive elements of the second elements board.
