ABSTRACT:
A miniaturized oxygen electrode comprising: an electrically insulating substrate; an electrolyte-containing material disposed on the substrate to form an electrolyte solution when water is introduced thereto; a set of component electrodes disposed on the substrate and connected with each other via the electrolyte-containing material; a gas-permeable membrane covering the electrolyte-containing material; the set of component electrodes including a cathode on which a reduction reaction of oxygen occurs and an anode as a counterpart of the cathode; the electrolyte-containing material being composed of a first layer and a second layer which are mutually connected, the first layer containing no electrolytes and being connected to the cathode and the second layer containing an electrolyte and being not connected to the cathode, the mutual connection of the first layer and the second layer being effected so that, during the water introduction and a subsequent holding, the electrolyte of the second layer diffuses to the first layer to form a single electrolyte solution layer.
