Abstract
An ultrasonic cleaner includes: a cleaning tank; an ultrasonic transducer; 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; and an air layer or a metallic member that is provided in an area formed by projecting at least the vibration head in the vertical direction under the cleaning tank, wherein the ultrasonic transducer is driven at a frequency at which the vibration head is vibrated resonantly in a vibration mode accompanied by a deformation in the longitudinal direction of the cylindrical hole and a direction perpendicular to the longitudinal direction, wherein an area formed by projecting at least the vibration head in the vertical direction in a bottom portion of the cleaning tank is formed of a material mainly including resin.
