Abstract
A heat-generating element of an electric heating device includes a PTC element, conductor tracks abutting surfaces of the PTC element, and an adhesive which connects the conductor tracks to the PTC element. The conductor track has several contact projections which protrude from an abutment surface of the conductor tracks. The contact projections form a contact surface which abuts the surface in an electrically conductive manner with a free space between the surface and the abutment surface, in which the adhesive is accommodated. Also disclosed is a method in which the contact projections are formed from initially planar conductor track, an adhesive is applied to the abutment surface between the contact projections, a masking covering the contact surfaces is removed, and the conductor track is glued to a PTC element with the adhesive accommodated between the surface and the abutment surface.
