Abstract
There is disclosed a method of easily producing a long-lived ion sensitive film having excellent durability and used in an ion sensor. The method starts with preparing a monomer mixture consisting chiefly of monomer units including a functional group and a second group of bonded atoms. The functional group has a function of identifying a certain chemical substance. The second group can become an active species that induces a polymerization or bridging reaction by being irradiated with an electron beam or radiation. Then, the monomer mixture is irradiated with the electron beam or radiation in a low energy range. Thus, the monomer mixture is polymerized.
