Abstract
A method for producing particles, the method including: applying vibration to a liquid including a physiologically active substance and included in a liquid-column resonance liquid-chamber to form a standing wave based on liquid column resonance, to thereby discharge the liquid from at least one discharging port, which is formed in an amplitude direction of the standing wave, to at least one region corresponding to at least one anti-node of the standing wave; and drying the liquid discharged, to thereby form particles.
