ABSTRACT:
Disclosed is an ion sensor having an ion-sensitive substrate provided within a tube at a position recessed from an open end of the tube and having an ion carrier membrane, which is selectively permeable to an ion of interest, filling the space between the opening of the tube and the surface of the ion-sensitive substrate on the open-end side of the tube. A method of manufacturing the ion sensor includes steps of inserting and retaining the ion-sensitive substrate in the tube, filling the space between the ion-sensitive substrate and the tube with a sol-like ion carrier membrane composition, and gelling the sol-like ion carrier membrane composition.
