Abstract
A sensor element for an electrochemical sensor, in particular for determining the oxygen content in exhaust gases of an internal combustion engine. The sensor element has at least one measuring electrode exposed to a measuring gas, at least one reference electrode exposed to a reference gas, at least one heating device having one heating conductor and two heating conductor leads, and a reference gas channel. The heating conductor has at least two heating circuit trace segments outside the vertical projection of the reference gas channel, the two heating circuit trace segments being connected by a connecting segment routed over the reference gas channel. The circuit trace cross section of the connecting segment is larger than the cross section of one of the heating circuit trace segments.
