An auxiliary heater for a motor vehicle has a layer structure comprising a heat generating element with at least one PTC heating element and printed conductors contacting the PTC heating element on both sides for powering the PTC heating element and at least one heat dissipating element, connected for thermal conduction with the heat generating element. A housing accommodates the layer structure as well as contact lugs for the connection of the auxiliary heater to a power source. For providing the best possible and simplist connection to a power source via a plug element, and with regard to the economical manufacture of the auxiliary heater, the contact lugs are formed by stamped sheet metal pieces which are electrically connected to selected printed conductors.
