Abstract
A method for supplying a viscous substance includes the step of providing a viscous substance having an adhesive characteristic which changes in correspondence to a polarity of a voltage applied thereto. The viscous substance has an adhesive characteristic when no voltage is applied thereto and its adhesiveness is reduced when a voltage is applied thereto. The method further includes the step of supplying the viscous substance between a pair of electrodes at least one of which has a pattern comprising an electroconductive portion and an insulating pattern. The method also includes the step of applying a voltage between the first and second electrodes to thereby attach the viscous substance in an amount which corresponds to the ratio of the area of the electroconductive portion to the area of the insulating portion.
