A rodlike ceramic member of a heater projects towards and into the active tip of the solid electrolyte tube of an oxygen sensor, extending out from the bottom end of the principal insulating member of the sensor which is made of the same ceramic material. Conducting paths of the heater are brought up to a shoulder where the wider insulating part joins with the carrier of the heater, for connection with conductors leading to the end of the main insulator which is remote from the measuring gas and, furthermore, on this shoulder, connections are also made between conducting paths of the solid electrolyte sensor probe and conductors leading to the end of the main insulator remote from the measuring gas. At that end of the main insulator, sleeve connections are made to connection wires for external connections.
