PURPOSE:To provide an ion selective electrode having excellent potential reproducibility. CONSTITUTION:An ion selective electrode comprises an ion sensitive film 11, an electrode housing 4 for holding the film, an inner electrode 2, and inner liquid 3 in contact with both the film 11 and the electrode 2, wherein properties of both the surfaces 11a of the film 1 are hydrophobic, thereby obtaining the sensitive film of the electrode having excellent fundamental characteristics such as excellent reproducible or selective characteristics of the electrode. |
