Zusammenfassung:To provide a total solid type ion-selective electrode of which stability of a potential or long-term stability of a detected value is increased.SOLUTION: A total solid type magnesium ion-selective electrode 1 includes: a conductor 2; an insertion material 10 formed on a surface of the conductor 2; and a magnesium ion sensitive film 20 over the insertion material 10. The insertion material 10 contains a Prussian blue analog represented by the structural formula of MgFe[Fe(CN)]nHO, in which x denotes a number from 0 to 1, both inclusive, y denotes a number larger than 0 and equal to or less than 1, and n denotes a number of at least 0.SELECTED DRAWING: Figure 2 【課題】電位の安定性や検出値の長期安定性を向上させた全固体型イオン選択性電極を提供する。【解決手段】全固体型マグネシウムイオン選択性電極１は、導体２と、導体２の表面に形成されたインサーション材料１０と、インサーション材料１０を覆うマグネシウムイオン感応膜２０とを備える。インサーション材料１０は、構造式ＭｇｘＦｅ[Ｆｅ（ＣＮ）６]ｙ・ｎＨ２Ｏで表されるプルシアンブルー類似体を少なくとも含み、ｘは、０以上１以下の数であり、ｙは、０よりも大きく１以下の数であり、ｎは、０以上の数である。【選択図】図２
