Abstract
A gas sensor element () includes a first composite ceramic layer () having a plate-shaped first surrounding portion () formed of an insulating ceramic and including a through hole inner-perimetric-surface () which defines a through hole (), and a plate-shaped first electrolyte portion () formed of a solid electrolyte ceramic, disposed in the through hole (), and including an electrolyte outer-perimetric-surface () in contact with the through hole inner-perimetric-surface (). The electrolyte outer-perimetric-surface () of the first electrolyte portion () is sloped toward an exterior of the first electrolyte portion () as it approaches one side DT. The through hole inner-perimetric-surface () and the electrolyte outer-perimetric-surfaceare in close contact with each other along their entire perimeters.
