PROBLEM TO BE SOLVED: To provide a solid electrolyte sensor in which mixing of gases in two spaces sandwiching a sensor element made of solid electrolyte ceramic is suppressed.SOLUTION: The solid electrolyte sensor 1 comprises a cylindrical holder 52, a bottomed cylindrical sensor element 51 made of solid electrolyte ceramics, and a sealing member 50 in which a cylindrical portion of the sensor element is connected to one end of the holder so that the closed internal space of the bottomed tubular is partitioned from the external space. A joint having a metallic annular member that is plastically deformed is used as a sealing member between male screw portions 11 and 12 and nut members 41 and 42 to be mated with the respective male thread portions. The metallic annular member is a pair of a front ferrule 21 and a back ferrule 31, and a pair of a front ferrule 22 and a back ferrule 32.SELECTED DRAWING: Figure 1 【課題】固体電解質セラミックス製のセンサ素子を挟んだ二つの空間のガスの混合が抑止されている固体電解質センサを提供する。【解決手段】固体電解質センサ１の構成を、円筒状のホルダ５２と、固体電解質セラミックス製で有底円筒状のセンサ素子５１と、ホルダの一端にセンサ素子の円筒部を接続することにより、ホルダの一端がセンサ素子で閉塞された有底筒状の内部空間を外部空間と区画している封止部材５０とを具備する構成とし、封止部材として、雄ネジ部１１，１２と、雄ネジ部それぞれと螺合するナット部材４１，４２との間で、塑性変形する金属製の環状部材（フロントフェルール２１とバックフェルール３１の対、及び、フロントフェルール２２とバックフェルール３２の対）を備える継手を使用する。【選択図】図１
