Abstract

The heater element (1) has a flat heating resistance (2) and at least two contact areas (4,4') spaced by the resistance. At least one of the contacts has a braid (6) which extends over a large length (8) with the resistance. The resistance is formed by multiple filaments and the length of the braid extension is between two and eight centimetres.
