Abstract
A gas sensor includes a solid electrolyte, a gas chamber, a reference gas chamber, a pump cell, a monitor cell, and a sensor cell. The gas chamber has a spatial width Wconstant in a width direction W orthogonal to the direction of flow of a gas in a position where the pump electrode, the monitor electrode, and the sensor electrode are provided on the solid electrolyte. An amount of shift ΔXof a central position Oof a gap S in the width direction W between the monitor electrode and the sensor electrode from a central position Oin the width direction of the pump electrode has relationship of ΔX≤¼ Wwhere the pump electrode has a width W. In addition, positions ΔYof a of a side surface of the monitor electrode and of a side surface of the sensor electrode from the central position Oin the width direction W of the pump electrode have relationship of ΔY≤½ W
