Abstract
An oxygen electrode having: an electrode substrate; a first electrode and a first lead wire formed on the electrode substrate; an insulating layer formed on the electrode substrate covering the first lead wire; a second electrode and a second lead wire formed on the electrode substrate, and on the insulating layer; a container substrate bonded to the electrode substrate, and having a first recess with an opening over the first and second electrodes for containing electrolyte; and an oxygen permeable film covering the opening. The oxygen electrode may be provided with lead plates and partially molded in an insulating and fixing resin. An oxygen electrode for measuring an oxygen concentration having a novel structure is provided which can be made more compact and/or be used more easily.
