Abstract

A gas sensor, in particular a lambda probe, for ascertaining the pollutant and/or oxygen content in emission gases of internal combustion engines, having a housing accommodating at least one sensor element, the sensor element having a section on the terminal side and a section on the measuring-gas side, and having a connecting element that connects the sensor element, which has a plurality of electrically conductive contact areas, at its terminal-side section to a plurality of electrically conductive supply leads. The gas sensor has the feature of a connecting element which is formed from a spring element produced in one piece from ceramic material.
