A gas sensor, in particular for determining the oxygen content in exhaust gases of internal combustion engines, is described. The gas sensor includes a sensing element sealedly fastened in a housing, whose segment on the measured gas side has at least one electrode exposed to a measured gas, at least one electrode exposed to a reference gas, and a reference gas conduit, extending in the longitudinal direction of the sensing element, which terminates at the segment of the sensing element remote from the measured gas and is connected to a reference gas source; and having contacts remote from the measured gas for making contact to the electrodes of the sensing element. Provision is made for the reference gas conduit to terminate at a large surface of the sensing element and to be sealed with a planar sealing fit.
