A gas sensor is described that includes a planar carrier membrane; a gas-sensitive layer on the carrier membrane; a first and at least a second electrode, which each lie on the gas-sensitive layer in an electrically conductive manner; and a first electric supply line to the first electrode and a second electric supply line to the second electrode. The second electrode lies radially outside the first electrode, and the first supply line is insulated with respect to the gas-sensitive layer.
