A rain sensor for the windshield of a vehicle has one or more electrically conductive layers which are arranged in a given pattern upon the outer surface of such windshield, and is constructed as a laminate of conductive and resistive layers formed by process steps of printing and sintering for construction of electrodes of the sensor. A conductive layer is formed of a mixture of electrically conductive particles and a glass frit which melts at a lower temperature than a melting temperature of the material of the window which serves as a support for the sensor. The conductive paste is applied with a heating action step, in the configuration of an electrode structure, by sintering to the window.

[ I claim:] [14.] A method of constructing a sensor for detecting moisture on a non-conductive pane of glass, in particular the windshield of a motor vehicle, the sensor comprising one or more electrically conductive layers which are arranged in a given pattern upon the outer surface of the pane of glass, the method comprising steps of:producing a conductive paste;applying said conductive paste on a side of a support sheet in said pattern, and drying said paste;covering the paste and the side of the support sheet bearing the conductive paste with a flexible foil layer wherein an adherence of the foil layer to the conductive-paste pattern is greater than an adherence of the support sheet to the conductive-paste pattern;separating said support sheet from said foil layer and said conductive-paste pattern, the later adhering to and being borne by said foil layer;applying said foil layer with said paste pattern on an outer surface of the pane of glass with said paste contacting the pane of glass; andheating said foil layer and said paste together with said pane of glass to accomplish a burning away of said foil layer and a sintering of the conductive paste on the pane of glass.
