PROBLEM TO BE SOLVED: To provide an oxygen sensor kit which is reliable in action, is easy in assembly and is recyclable. SOLUTION: This oxygen sensor kit is constituted to include a unit 1 by a supporting body 10 which is formed with a spherical surface part 11 at its front end, a metallic plate material 12 which is housed in the central region of this spherical surface part 11 so as to expose its surface and constitutes a working electrode connectable outside by a lead wire 14 and a metallic plate material 24 which is fixed to the flank part of the supporting body 10 and constitutes a counter electrode connectable to the outside by this lead wire 23. As a result, the metallic plate material 12 constituting the working electrode is fixed to the spherical surface part 11 at the front end and the metallic plate material 24 constituting the counter electrode to the flank thereof and, therefore, an oxygen permeable membrane is spread so as to be formed as thin as possible in the layer thickness of the electrolyte near the working electrode. In addition, the easy hermetic fixation by elastic fasteners is made possible.
