Abstract
A method of producing an electric heating device, in particular for automotive application, includes steps of: cutting through a sheet of electrically highly conductive material of appropriate thickness for obtaining a predetermined line pattern having at least one electrically conductive line with electrically conductive bridge members interconnecting portions of the at least one electrically conductive line; depositing a layer of curable adhesive material onto a surface of a dielectric, planar, flexible carrier; placing the obtained line pattern onto the layer of adhesive material; curing the adhesive material below the line pattern with the exception of the adhesive material below the bridge members; cutting through each bridge member at all ends between portions of the at least one electrically conductive line interconnected by the respective bridge member; and removing the cut bridge members.
