PROBLEM TO BE SOLVED: To provide a cathode for an oxygen electrode capable of constituting an oxygen electrode which can be stably used over a long period. SOLUTION: With a precious metal electrode 1 of platinum, etc., partially exposed so as to form the same surface as the surface of a supporting body 2, the precious metal electrode 1 is fixed in the supporting body 2 formed of a thermoplastic resin such as polyethylene terephthalate, and a cathode can be electrically connected to the outside of the supporting body 2 through a connecting terminal 1b. In this case, a small chamber 3 with a predetermined empty capacity is provided on the surface of the supporting chamber 2 in the vicinity of the exposed part 1a of the precious metal electrode 1 at a predetermined distance from the exposed part 1a of the precious metal electrode 1. |
