An electrical resistance heating element for a heating device, with at least one flow canal through which the gaseous medium is able to flow from a canal inlet side to a canal outlet side of the resistance heating element, and with at least one heating resistor that extends essentially in the direction of the flow canal, with the medium flowing past the heating resistor and being heated in the process. The heating resistor is rod-shaped and produced from an electrically conductive ceramic material. The electrical resistance heating element is intended for installation in a heating tube into which air, for example, is blown at one end. The heated flow of air exits from the other end of the heating tube.
