Abstract
A gas sensor is equipped with a housing, an insulator retained by an inner periphery of the housing, a sensing device having a front end portion protruding from a front end surface of the insulator, and a protective cover which covers a front end portion of the sensing device. A pump electrode and a sensor electrode are disposed in a front end portion of the solid electrolyte body. The pump electrode is exposed to a measurement gas and regulates the concentration of oxygen in the measurement gas. The sensor electrode is exposed to the measurement gas and measures the concentration of a given gas component in the measurement gas after being regulated in concentration of oxygen by the pump electrode. A base end portion of the sensor electrode in a lengthwise direction is located closer to a base end side of the gas sensor than a front end surface of the housing is. This minimizes a variation in temperature of the sensor electrode and enhances the accuracy in measuring the concentration of the given gas component.
