A gas sensor includes: a first electrode; a metal oxide layer that is on the first electrode and has a resistance value that changes when the metal oxide layer contacts hydrogen atoms; a second electrode on the metal oxide layer; and an insulating film that covers at least a part of side surfaces of the first electrode, the metal oxide layer, and the second electrode. In the metal oxide layer, a part of a first interface between the first electrode and the metal oxide layer is not covered by the insulating film and is exposed to a gas.
