ABSTRACT:
There are provided a method and an apparatus for removing electrostatic charges from high resistivity liquid. An insulating film is formed on the surface of a conductive element which is in contact with the high resistivity liquid wherein the insulating film has such a thickness that a tunneling current may flow through the insulating film, thereby preventing the highly purified high resistivity liquid from being contaminated, as well as from becoming acid. Thus, objects to be treated with the high resistivity liquid become free of electrostatic charges without any contamination.
