PROBLEM TO BE SOLVED: To provide an ultrasonic soil eliminator, which eliminates a stain on clothes or the like or mold formed on a bathtub or the like. SOLUTION: In the ultrasonic soil eliminator, a brush 2 is attached to the end of a case 1, inside of which an ultrasonic oscillator 3 is supported by a supporting member 3c fixed between an ultrasonic horn 3a and a front block 3b. The ultrasonic horn 3a is fitted to project almost at the center of the brush 2, which is formed to be long enough to extend slightly further from the front end of the ultrasonic horn 3a. A piezoelectric material oscillator 4 is inserted between the front block 3b and a rear block 3d of the ultrasonic oscillator 3, and is fixed integrally with the blocks via a bolt 5.
