Abstract

A gas sensor is disclosed which comprises a sintered metal oxide the resistance value of which changes with the ambient temperature, a gas sensor element having at least one electrode connected to the sintered metal oxide, a ceramic insulator for insulatively holding the gas sensor, a lead connection and a lead wire connected between the electrodes. The diameter of the ceramic insulator for passing the lead wire is reduced and the length of the electrode is shortened, thus realizing a compact gas sensor.
