To provide an anion selective electrode having high ion selectivity and having a short time until potential is stable, and a method for manufacturing the same.SOLUTION: An anion selective electrode comprises: an electrode housing 22 having a space for putting an internal solution; an inner electrode 24 contacting the internal solution; a first surface 21a; a second surface 21b positioned on the side opposite to the first surface; and an anionic exchange membrane 21 arranged between the internal solution 23 and a sample solution. A part of a second surface of an anion sensitive film is exposed so as to contact the sample solution, and at least a part of the second surface of the anion sensitive film is coated with an epoxy amine resin 26.SELECTED DRAWING: Figure 9 【課題】高いイオン選択性を有し、電位が安定するまでの時間が短い陰イオン選択性電極及びその製造方法を提供する。【解決手段】陰イオン選択性電極は、内部液を入れる空間を有する電極筐体２２と、内部液に接する内部電極２４と、第１面２１ａと、第１面に対して反対側に位置する第２面２１ｂとを有し、内部液２３と試料液との間に配置された陰イオン交換膜２１と、を有し、陰イオン感応膜の第２面の一部は、試料液と接することができるように露出しており、陰イオン感応膜の前記第２面の少なくとも一部がエポキシアミン樹脂２６で被覆されている。【選択図】図９
