SOLUTION: A dishwasher is provided with a washing water housing part 36 housing the washing water and an ultrasonic vibration part 37 for splashing the washing water inside a washing tub 22, and the washing water raised from a water surface by the vibration of the ultrasonic vibration part 37 is recovered so as to be in contact with the detergent fed to the washing water housing part 36. Even in the case of atomizing and splashing the washing water of a high detergent concentration by utilizing an ultrasonic vibrator 38, very little washing water is required, and the detergent components of alkali, a surfactant and a bleaching agent, etc., act on stains by the high concentration and strongly remove the stains.
