A sensor arrangement has a layer sequence that includes a holding substrate, an auxiliary layer, a detection layer and an insulating layer. The holding substrate holds detection elements. The auxiliary layer extends continuously over the detection elements or contains separate regions which are associated with a detection element. The detection layer has separate detection regions which are contained in a detection element and contain at least one semiconductor component which is sensitive to radiation. The insulating layer has separate insulating regions for electrically insulating the detection regions from a point of contact having electrically conductive connections and pads fitted on the free side. The pads are electrically connected to connecting points which are routed to the semiconductor components. This sensor arrangement can be used for detecting X-ray radiation and can be manufactured with particular ease.
