Abstract

The invention relates to a sensor element, particularly for an electrochemical measuring sensor, for determining the oxygen content of gases, having a first electrode, which is exposed to a gas to be measured, a second electrode, which is exposed to a reference gas, a heating device for the sensor element and a reference gas conduit extending between the heating device and the second electrode. It is provided that the reference gas conduit (20) is configured so as to be branched at least in the region of the heating device (30).
