1. A method for producing a heat-generating element, comprising:
placing at least two electrical conductor elements onto a film provided with an adhesive mass, wherein the conductor elements are provided with through holes and support points;
pressing the electrical conductor elements against the film such that the mass is forced into the through holes such that the conductor elements are pressed into the mass, so that the support points of the conductor elements lie approximately at approximately a same height as an outer surface of the mass;
subsequently placing at least one PTC element onto one of the conductor elements; then placing the other of the conductor elements, together with the film, opposite to the one of the conductor elements onto the PTC element; and
disposing a rod onto the mass at an end side of the PTC element and between the at least two conductor elements.
