Abstract
A gas sensor includes an insulation layer and detection cells covered with the insulation layer. Each of the plurality of detection cells includes: a first electrode; a second electrode having a surface exposed from the insulation layer; and a metal oxide layer disposed between the first electrode and the second electrode. In each of the detection cells, a resistance value of the metal oxide layer decreases with a response time, which is different in each of the detection cells, when a gas containing a hydrogen atom comes into contact with the second electrodes.
