A metal bar with a metal felt covering on each side or therearound and sized externally to be a snug slip fit into slot means provided in a conductive surface monolithic refractory ceramic heater element provide for a convenient and desirable means for distributing current to the conductive surface of the element. As the felt covered electrode means heats up with electric current input to the element and under heat generating conditions, there will be a still tighter bond between the metal felt surfaces of the electrode and the slotted opening in the ceramic element to result in the desired tight contact and an efficient current distribution therefrom.
