Abstract
The present invention addresses the problem of improving both ion-selective electrode stability and adhesion between a sensitive film and a casing. This ion-selective electrode is characterized by being provided with: a sensitive membrane containing an ion-selective substance, a substrate, and a plasticizer; and a casing that holds the sensitive membrane, and by the casing material containing a substance having a solubility parameter (SP value) of 19.5 to 21.5.
