PROBLEM TO BE SOLVED: To provide an ion sensor wherein chlorine ion selectivity is improved. SOLUTION: A chorine ion sensitive film which uses an anion exchange resin film shown in an equation, an internal solution housing vessel provided with the sensitive film, and an internal electrode allocated in the vessel are provided. Where, in the equation, R1-R3 are alkyl group of carbon number 6 or more while 1<=n<=10. In addition, Z is a group selected among hydrogen, alkyl group, cyano group, and halogen group, while X<-> is an atomic group which constitute halogen ion or anion. |
