Abstract
The present invention relates to an electrified object neutralizing method and a neutralizing device. The present invention is characterized in that electrons are made released by means of a photoelectric effect, negative ions are generated by making the released electrons combine with gas-state atoms or molecules, and positive electric charge in an electrified object is neutralized by the negative ions. With the features, electrification of an object can be prevented without contaminating the object.
