Abstract
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.
