Disclosed is a gas sensor comprises a ceramic substrate, heaters formed on the surface of the substrate, an insulating layer formed as superposed on the heaters, electrodes formed on the surface of the insulating layer and a catalyst layer made of a gas detecting substance and formed as superposed on electrodes, and further disclosed is a method for the production of a gas sensor comprises the steps of forming a substrate of a ceramic substance, forming heaters on the surface of the substrate, forming an insulating layer for the substrate as superposed on the heaters, forming an electrode parts on the surface of the insulating layer and forming a catalyst layer made of a gas-detecting substance and superposed on the electrodes.
