Abstract
A gas sensor element that includes a composite ceramic layer including a plate-shaped insulating portion which contains an insulating ceramic and has a through-hole, and an electrolyte portion which contains a solid electrolyte ceramic, and a portion disposed in the through-hole where the electrolyte portion is thicker than the insulating portion. A first conductor layer is formed over a first insulating surface of the insulating portion and a first electrolyte surface of the electrolyte portion. The electrolyte portion has an extending portion which is overlaid on the first insulating surface and extends toward the outside of the through-hole. The thickness of the extending portion is decreased toward an outer periphery of the extending portion, and the outer periphery of the extending portion is continuously connected to the first insulating surface. A first extending surface of the extending portion continuously connects the first insulating surface and the first electrolyte surface.
