An ion sensor includes: a conductive base structure including a substrate and an electrode film formed on the substrate; a plurality of ion-sensitive nanorods protruding from the electrode film; and an encapsulant enclosing the conductive base structure, surrounding the ion-sensitive nanorods, and formed with a window for exposing the ion-sensitive nanorods. Each of the ion-sensitive nanorods has a conductive core and an ion-sensitive layer formed on and enclosing the conductive core. The ion-sensitive material exhibits an ion selectivity of absorbing an ion of interest thereon for inducing a surface potential corresponding to concentration of the ion of interest.
