Abstract
A flat shaped composite electrode includes a flat substrate having a high electrical insulating property. A flat inside pair of electrodes and a flat outside pair of electrodes are fixed on the substrate. A flat support layer having a high electrical insulating property overlays the electrodes and substrate. The support layer describes two holes into which a gelatinized internal solution is placed. An ion response glass membrane is mounted on the support layer and over one hole, while a liquid junction membrane is similarly mounted over the other hole.
