Zusammenfassung:PURPOSE: An ultrasonic cleaning device is provided to stably operate an ultrasonic oscillation element without requiring a complicated structure and circulation of a large quantity of cleaning solvent and to easily clean both upper and lower surfaces of an object to be cleaned. CONSTITUTION: An ultrasonic cleaning part has an upper cleaning solvent supplying nozzle(12) and a lower cleaning solvent supplying nozzle(14). The upper cleaning solvent supplying nozzle(12) supplies an upper surface cleaning solvent(13) to the upper surface of a glass substrate(11). The lower cleaning solvent supplying nozzle(14) supplies a lower surface cleaning solvent(15) to the lower surface of the substrate(11) as a shower irradiated with ultrasonic waves. An oscillation element which oscillates the ultrasonic waves irradiating the lower surface cleaning solvent(15) is installed in a circulation passage for the cleaning solvent(15), which passage extends from the upstream side to the downstream side, in the direction between the horizontal direction and the upward direction.
