An electric heating device includes a casing that forms inlet and outlet openings for the fluid to be heated and a circulation chamber as well as a connection chamber separated from the circulation chamber by way of a partition wall. A heat-emitting surface of a PTC heating element is exposed in the circulation chamber and is coupled in a heat-conductive manner to a PTC element. The PTC element is in electrically conductive contact, which via electrical conductor tracks with different polarities that are electrically connected in the connection chamber. The casing is a plastic casing provided with a shielding.
