A gas sensor comprising a layer of sintered tin oxide having a large specific surface area and high activity to oxidize and eliminate alcohol, benzene and other miscellaneous gases, whereby the sensor selectively detects alkane gases such as methane gas, propane gas and butane gas. The alkane gas is absorbed thereby decreasing an electrical resistance of the sensor in order to detect the existence of the gas.
