Zusammenfassung:	To suppress precipitation of a cleaning solution to a vibration head of an ultrasonic cleaner. An ultrasonic cleaner includes: a cleaning tank which stores a cleaning solution; an ultrasonic transducer; and a vibration head which extends from the ultrasonic transducer toward the cleaning tank and of which a tip portion includes a cylindrical hole having a longitudinal direction aligned to a vertical direction, wherein the ultrasonic transducer is driven at a frequency at which the vibration head is vibrated resonantly, and wherein the vibration head is provided with a hydrophobic or hydrophilic coating film 502 which has an interface between an area 223 corresponding to a vibration antinode and area corresponding to a vibration node during the resonant vibration of the vibration head, and covers the area 222 corresponding to the vibration node.
