(57) Abstract The electrochemistry measurement sensor (10) in order to measure, especially the oxygen content in the exhaust gas of the internal combustion engine in order potential dying has possessed the sensor component (14) which, is laid out to measure the oxygen content of the gas is proposed. As for the sensor component (14), the oxygen ion outside conducts, is laid out on the external surface the electric conduction path (27) of the contact breaker points side which extends to the external surface in the same way and also it has possessed the electrode (25), we have possessed the solid-state electrolytic body (23) of forma of the tube where one side is blocked, at the same time, it is inserted in the metal casing (11) by the seal ring (20). The sensor component (14) at least inside the range of the seal ring (20), has had the electric insulating formation (21) at least canning the electric conduction path (27) vis-a-vis the casing (11). This insulating formation (21) consists of the blend of the non-metallic substance and the glass conversion material of crystalline. The case of the production, the heat treatment which in insulating formation (21) exceeds the melting point of the glass conversion material is done, in this case, insulating formation (21) forms the glaze restoration with the non-metallic substance of crystalline.
