1. A heat-generating element comprising:
a PTC element;
conductor tracks abutting surfaces of the PTC element; and
an adhesive which connects the conductor tracks to the PTC element, wherein
the conductor tracks each have an abutment surface extending parallel to the associated surface of the PTC element, wherein
a plurality of contact projections, formed by the conductor tracks, protrude from the abutment surface of each of the conductor tracks, wherein
each of the projections forms a contact surface which abuts the associated surface of the PTC element in an electrically conductive manner and forms a free space between the associated surface of the PTC element and the abutment surface of the conductor track, and wherein
the adhesive is accommodated in the free space.
