Claim:
1. A moisture sensor for monitoring an access to a patient for a system by which, via a flexible line, a liquid is fed at least one of to the patient or from the patient, or for monitoring a vascular access in extra-corporeal blood treatment, the moisture sensor comprising: a substrate material to be applied to the patient's skin, the substrate material including an electrically conductive structure, wherein the substrate material has a narrowing extension that forms a connection section, wherein the electrically conductive structure has at least a first and a second conductor path, the at least first and second conductor paths being arranged at a distance from one another, wherein the at least first and second conductor paths each have one end forming an electrical contacting portion and another end forming an electrical connecting contact, wherein the electrical contacting portions are connected together across a terminating resistor, wherein the electrical connecting contacts form an electrical connection for the moisture sensor, wherein the terminating resistor is an electrically conductive film applied to the connection section, wherein the electrically conductive film extends over the connection section where the electrical contacting portions are situated, and the electrically conductive film lies on the electrical contacting portions, wherein the electrical contacting portions and the electrical connecting contacts are located on the narrowing extension that forms the connection section, and wherein the electrically conductive film and the substrate material are adhesively bonded together by a conductive adhesive.
