An X-ray detector comprising a converter element with a rewiring unit has a stack arrangement comprising a converter element, a rewiring unit and an evaluation unit. The converter element has a firstelectrode on a surface facing away from the evaluation unit and a pixelated second electrode having a plurality of electrode elements on a surface facing toward the evaluation unit. The evaluation unit has pixel electrodes. The rewiring unit is embodied on a surface of the converter element facing toward the evaluation unit, first contacts of electrically conductive connections between the electrode elements and the pixel electrodes being provided on a surface of the rewiring unit facing toward the converter element and having a first areal distribution, and second contacts of the electricallyconductive connections between the electrode elements and the pixel electrodes being provided on a surface of the rewiring unit facing toward the evaluation unit and having a smaller second areal distribution compared to the
