An object of the invention is to provide a structure of an oxygen electrode which can be formed with a cost enabling disposal. The invention provides an oxygen electrode (2) used to measure an amount of dissolved oxygen in a liquid culture medium. The oxygen electrode (2) according to the invention is equipped with an electrode base material (10), and a surface metal layer (13) is any one of Au, Pt, and Ti and covers a surface of the electrode base material (10). Especially, in a case where the surface metal layer (13) of Au is formed on the electrode base material (10) of copper with electroplating, a nickel layer (11) is formed on the surface of the electrode base material (10) by layering with electroplating, etc. Then, the Au layer (13) is formed on the nickel layer (11) by layering with electroplating, etc. |
