A sensor element for detecting at least one property of a measuring gas in a measuring gas chamber, in particular for detecting a proportion of a gas component in the measuring gas or a temperature of the measuring gas, includes a ceramic layer construction that includes at least one electrochemical cell, the electrochemical cell having at least one first electrode, a second electrode, and at least one solid electrolyte connecting the first electrode and the second electrode. The second electrode is situated in the layer construction facing an electrode cavity that is in the layer construction. The second electrode has at least one outer diameter that is greater than a corresponding outer diameter of the electrode cavity.

Sensor element for detecting at least one property of a measuring gas in a measuring gas chamber

The invention relates to an electrode coil for a galvanic element, comprising a first electrode (), a second electrode (), a separator, and a reference electrode (). The first electrode () and the second electrode () are insulated from each other by the separator, and the reference electrode () is arranged between the first electrode () and the second electrode () and is adhered to the first electrode () or to the second electrode (). The invention further relates to a galvanic element comprising such an electrode coil and to a method for producing such an electrode coil.
