    • An electrochemical sensor (10) is disclosed wherein ion impermeable plugs (30) are interposed between the adjacent faces (24a) of the large plugs (24) that are used in the salt bridge. The salt bridge also includes a second series of solid cylindrical semi permeable plugs (30) that pass through the ion impermeable plugs and thereby interconnect the adjacent large plugs. The large plugs have a central bore (26) for receiving the glass sensing electrode (16). The impermeable plug has protrusions (40) to provide a better seal between the impermeable plug and the glass sensing electrode and the impermeable plug and the housing (12) in which the salt bridge is inserted. In addition, the sensor may also include a rigid liner (60) between the large plugs and the glass sensing electrode to act as a barrier to prevent damage to this sensing electrode during and after impregnation.

    • A glass electrode having a sheet type shape and being open toward an upper sur­face side is described. This sheet type glass electrode provides together with a sheet type reference electrode a sheet type composite electrode wherein the glass electrode and the reference electrode are placed side by side under the condition that they are open toward an upper surface side. This sheet type glass electrode comprises a substrate (10) formed of a material having a sufficiently high electrical insulating property, an electrode (D) comprising an internal electrode portion (B) and a lead portion (C) stuck to an upper surface thereof, a support layer (F) formed of a material having a sufficiently high electrical insulating property which is provided with a hole (E) at a place corresponding to said internal electrode portion (B) being formed on the upper surface of said substrate (A) under the condition that said lead portion (C) and its circum­ference are exposed, said hole (E) in the support layer (F) being tightly filled with a gelatinized internal solution (G) and a flat plate-like ion-response glass membrane (H) which is fixedly mounted on the upper surface of said support layer (F) along a circumference thereof by the use of adhesives (I) having a suffi­ciently high electrical insulating property so that a lower surface therof may be closely stuck to an upper surface of said gelatinized internal solution (G).
