Exhaust gas sensor

A gas sensor, for example, a gas sensor for detecting at least one gas component in an exhaust gas is provided, in which a sensor element is situated in a metal housing. At a connection-side end of the housing, in a contact area, the sensor element has a support element, in which at least one partial area of at least one contact is situated. A porous material is situated between the support element and the housing. In the contact area, the housing includes at least one aperture. A flow path is situated along an outer surface of the support element, so that the exhaust gas, which may be located outside the gas sensor, may reach a connection-side end of the sensor element through the aperture in the housing, through the porous material and via the flow path along the outer surface of the support element.
