Abstract: A gas sensor includes a sensitive portion and a plurality of electrodes arranged via the sensitive portion. The sensitive portion includes an ionic liquid and is configured to have electrical resistance that changes when the sensitive portion adsorbs a gas molecule. The ionic liquid preferably includes a hydrophobic anion. The hydrophobic anion preferably includes an organic fluorine compound. The organic fluorine compound preferably has a trifluoromethyl group.
