Abstract

A ceramic gas sensor for measuring a gas component in a gas mixture, which includes a sensor element, which has at least one first electrode exposed to the gas mixture to be determined, and at least one further electrode. Only one shared electrical contact is provided for the first electrode and for the additional electrode, an electrical resistor, which is situated inside the gas sensor, being preconnected to the first electrode and/or the additional electrode.
