Abstract
To propose a gas sensor and a gas sensor structural body that can improve detection sensitivity of gas more than in the conventional gas sensors with a simple configuration. A graphene (8) between a source electrode (3) and a drain electrode (4) is provided in an ion liquid (L), whereby a state change of charges in the ion liquid (L) caused by absorption of gas is directly reflected on a source-drain current (Isd) that flows in the graphene (8). Therefore, it is possible to improve detection sensitivity of the gas more than in the conventional gas sensors. The graphene (8) only has to be provided to be disposed in the ion liquid (L). Therefore, unlike in the conventional gas sensors, a configuration in which carbon nanotubes are surface-chemically modified by a plurality of polymers is unnecessary. Therefore, it is possible to simplify a configuration.
