A heating set having a plurality of positive temperature coefficient thermistor heating elements (PTCR pieces) sandwiched between two heat radiating devices made of metal with each of the PTCR pieces provided with sprayed-on electrodes having their exposed surfaces making close contact with long metal battens on the outer surfaces of the heat radiating devices through conducting thin metal pieces having predetermined surface areas. The PCTR pieces and the heat radiating devices making electrical contact through the thin metal pieces are bonded together by an electrically nonconductive adhesive spread on the border of the battens around the thin metal plate and on opposite parallel edges on the border of the sprayed-on electrodes of the PTCR pieces.
