The invention relates to a gas sensor for detecting gas in the air, especially formaldehyde. The sensor comprises at least one gas-sensitive zone which is preferably a layer on a substrate and which contains the ternary compound In4Sn3O12 as the gas-sensitive material. In order to produce the gas-sensitive zone, a flame spray pyrolysis (FSP) is carried out, organometallic compounds of indium and tin being used as the reactants. The gas sensor is especially suitable for online gas detection.
