This invention relates to an electrical conductor () which is composed at least partially of an electrically conductive material. According to the invention, at least part of the electrical conductor () is provided with a protective layer () whose specific electrical conductivity is lower, at least locally, than that of the electrically conductive material of the conductor ().

Electric conductor

The invention relates to a heating element (), in particular for heating user contact surfaces of a passenger compartment of a vehicle, comprising a) at least one heating zone in which at least one first electrical conductor strand is disposed for heating a passenger of the automotive vehicle; b) at least one additional second conductor strand for supplying electrical energy into the at least one first conductor strand for heating the heating zone; c) a contact area in which the at least one additional second conductor strand is connected, in an electrically conductive manner, to the at least one first conductor strand for heating the heating zone; and wherein at least one of the first or second conductor strands includes at least one filament-like inner strand core comprising a polyamide, a carbon fiber, a polypropylene, or a polyester and at least one jacket layer that includes silver, copper, gold, nickel, or an alloy thereof.
