Abstract
A gas sensor element including: a solid electrolyte layer having a first surface and a second surface; a first electrode formed on the first surface of the solid electrolyte layer; a second electrode formed on the second surface of the solid electrolyte layer; and an insulating layer provided between the first electrode and the first surface of the solid electrolyte layer. The insulating layer covers an outer edge of the first electrode and has an opening through which a portion of the first electrode is exposed. The opening has an area that is smaller than that of the second electrode, and is provided at a position opposite the second electrode to form a detection portion constituted by the portion of the first electrode exposed through the opening, the second electrode and the solid electrolyte layer.
