The present invention relates to an ultrasonic transducer provided in the cleaning tank bottom or the side of the washer. And the ultrasonic transducer of the present invention comprises a piezoelectric ceramics, and electrodes for applying power to a piezoelectric ceramic and, as the blocks are vibrated by the piezoelectric ceramic, the fastening means comprising a stud and a nut, in particular the upper vibration block has a top the various grooves in the surface shape is formed. Then, the upper vibration block and groove is formed on the top surface so as to improve the mechanical bunjil coefficient ( "Qmeff") that determine the cleaning ability of the cleaner, preferably a width of the groove is 1~2mm and depth of the upper vibration block It formed 1 / about 3-1 / 2 in the vertical direction length.
