Abstract
To provide a gas sensor with fast response and high sensitivity to oxygen gas. Disclosed is a gas sensorincluding: a substratea first pad electrodeA and a second pad electrodeB; a nanowiremade of a specific metal; and an oxide layermade of a high-resistance semiconductor that is an oxide of a metal different from a metal constituting the nanowireThe first pad electrodeA and the second pad electrodeB are formed on or above the substrateThe nanowireconnects the first pad electrodeA and the second pad electrodeB and is formed on or above the substrate The oxide layeris formed in contact with the nanowireThis contact between the nanowireand the oxide layerprovides fast response and high sensitivity to oxygen gas.
