摘要： An electric heating device includes a substrate and a heat conductor layer formed on the substrate. The heat conductor track includes a plurality of track sections which run adjacently to one another and are separated from one another by insulating interruptions. At least one reversal point is provided at which the heat conductor track is deflected such that inner track sections with opposite flow directions run adjacently and parallel to one another. The spacing between the adjacent inner track sections is locally expanded in the region of the reversal point where the inner track sections protrude outwards to outer track sections, and the width of the track sections is locally reduced in front of and in the outer track sections to compensate for the local expansion on the inner face between the inner track sections and for the protrusion of the inner track sections.
