Abstract: Provided are a bubble ejection method based on a novel principle, a power supply device used for performing the bubble ejection method, and a bubble ejecting apparatus. A bubble can be ejected by a bubble ejection method for bubble ejection into a conductor, the bubble ejection method includes steps of: contacting a bubble generating electrode to a conductor; contacting a counter electrode to the conductor or a processing target; and applying a negative voltage to the bubble generating electrode, and a conductive material is exposed on at least a tip part of the bubble generating electrode.
