To provide an ultrasonic cleaning machine which radiates an ultrasonic wave from a plurality of vibration surfaces, radiates the ultrasonic wave in the same phase, effectively generates a cavitation by an ultrasonic vibration in the periphery of a nozzle, and has a high cleaning effect.SOLUTION: An ultrasonic cleaning machine 26 includes: a cleaning tub 202 for cleaning a nozzle 22 to suck a sample or a reagent; and an ultrasonic vibrator 201 obtained by holding piezo-electric elements 205 between a front mass 204 and a back mass 207. Vibration plates being an upper plate and a lower plate which are opposing each other are formed at a distal end of the front mass 204 to be arranged at the tip end of the ultrasonic vibrator 201. The nozzle 22 is cleaned by an ultrasonic wave in an area between the upper plate and the lower plate.SELECTED DRAWING: Figure 2B 【課題】複数の振動面から超音波を照射し、同位相で超音波を照射し、超音波振動によるキャビテーションをノズルの周囲に効果的に発生させ、洗浄効果が高い超音波洗浄機を提供する。【解決手段】超音波洗浄機２６は、サンプル又は試薬を吸引するノズル２２を洗浄する洗浄槽２０２と、圧電素子２０５をフロントマス２０４とバックマス２０７とで挟み込んだ超音波振動子２０１と、を有し、超音波振動子２０１の先端に設置されるフロントマス２０４の先端には、対向する、上板と下板との振動板を形成し、ノズル２２を、上板と下板との間の領域で、超音波洗浄する。【選択図】図２Ｂ
