Abstract

A gas sensor is equipped with a solid electrolyte body, a pump electrode, a sensor electrode, and a heater. In the gas sensor, a region of the whole of a front end portion of a heater base in which a heating element is disposed is broken down into three regions: an intermediate region defined between a front end and a base end of the sensor electrode, a front end region located closer to a front end side than the intermediate region is, and a base end region located closer to a base end side than the intermediate region is. A resistance value per unit area of a heating element lying in the base end region and a resistance value per unit area of the heating element lying in the front end region is selected to be higher than that of the heating element lying in the intermediate region, thereby keeping the temperature of a region around the sensor electrode at a desired level even when the temperature of gas changes.
