WIPO Patent Application WO/2022/224763
Kind Code:
A1
Abstract:
This gas sensor comprises a sensor element (2). The sensor element (2) has a solid electrolyte body (3), a detection electrode (4A), and a reference electrode (4B). The solid electrolyte body (3) has a bottomed cylindrical shape and is composed of a solid electrolyte material having ion conductivity. The detection electrode (4A) is provided outside the solid electrolyte body (3) in a state of being exposed to to-be-detected gas (G). The reference electrode (4B) is provided inside the solid electrolyte body (3) in a state of being exposed to reference gas (A). A porous layer (23) having a large number of pores is provided between the solid electrolyte body (3) and the reference electrode (4B).
