Electrochemical sensor

A electrochemical sensor for determining at least one of gas components and gas concentrations in gas mixture, the sensor comprising a sensor element, the second element comprising:

• a first solid electrolyte layer containing a gas channel;
• a second solid electrolyte layer;
• an electrode including an electrode surface and an electrode lead, the electrode being situated in a first, clamped region between the first and second solid electrolyte layers and in a second, open region between the second solid electrolyte layer and the gas channel;
• and
• at least one foil-bonding layer situated between the electrode and one of the first and second solid electrolyte layers, and wherein, in a transition region between the first region and the second region, at least one of the at least one foil-bonding layer is left out.
