Abstract
In order to provide a planar type multi-ion sensor which is easily thinned and has high measurement accuracy, a multi-ion sensoradapted to measure a concentration ratio of sodium ions to potassium ions in a sample solution, includes: a sodium ion electrodeselectively reacting to the sodium ions; a potassium ion electrodeselectively reacting to the potassium ions; and a common electrodein contrast with the sodium ion electrodeand the potassium ion electrode, wherein the sodium ion electrode, potassium ion electrodeand common electrodeare provided on the same support body, the common electrodedoes not include internal solution, and the concentration ratio of the sodium ions to the potassium ions is measured based on a variable A that is obtained by the following Equation (1),
