Abstract
A semifinished product of an electric heater device () has a structure that extends in a length direction (L) and that comprises: —two connection bodies (), which substantially extend alongside one another or parallel to one another in the length direction (L) and are at least in part flexible or deformable in the length direction (L); and —a plurality of heating bodies (), each heating body () including a material having a PTC effect. The heating bodies () are set at a distance from one another in the length direction (L) and generally extend in a direction transverse to the length direction (L). The material having a PTC effect is a polymer-based material that is in electrical contact with the at least two connection bodies (). Each of the at least two connection bodies () comprises electrical- and mechanical-connection parts (), which have a mesh structure that is at least partially embedded or englobed in the polymer-based material.
