- *Abstract
-
Provided is an ion sensor with which the concentration ofions in a solution can be determined without any reference electrode. The ion sensor isequipped with: a first electrode
plate; a second electrode plate which has been disposed opposite the firstelectrode plate and has one or multiple openings; an ion-sensitive film continuously formed sothat the film is interposed between the firstelectrode plate and the second electrode plate, blocks up one side of each opening of the second electrode plate, and extends from the end of thatside of the opening to the outer surface of the second electrode plate through the inner wall surfaceof the opening; and a sensor support which supports the second
electrode plate so that when the ionconcentration of a test solution to be examined is determined, the ion-sensitive filmcomes into contact with the testsolution only in the portions thereof that have been formed in each opening andon the outer surface of the second electrode plate. The ion sensor isconfigured so that the thickness of the ion-sensitive film interposed betweenthe first electrode plate and the second electrode plate is different from thethickness of the ion-sensitive film formed on the outer surface of the secondelectrode plate. A difference in potential between the first electrode plateand the second electrode plate is measured.
