To provide an ultrasonic cleaner which has a constitution suitable for mounting in a narrow space such as a carrying rack and is reduced in liquid surface fluctuation, liquid level variation, and mist generation and can irradiate an outer peripheral part of a nozzle with a powerful ultrasonic wave.SOLUTION: The ultrasonic cleaner includes: a cleaning tank having a liquid storage part for storing therein a liquid; and an ultrasonic vibrator having a piezoelectric element and a front mass. A through hole having openings on an outer wall surface of the cleaning tank and an inner wall surface of the liquid storage part is provided in a side surface part of the cleaning tank, and the front mass is inserted to the through hole, and a cover is installed so as to cover a space above a front end surfaces of the front mass, and the cover is movable at least upward.SELECTED DRAWING: Figure 2B 【課題】搬送ラックのような狭小空間への搭載に適した構成を有し、液面の揺れ、液位の変動及び霧の発生が少なく、ノズルの外周部に強力な超音波を照射可能な超音波洗浄機を提供する。【解決手段】液を貯める貯液部を有する洗浄槽と、圧電素子及びフロントマスを有する超音波振動子と、を含む超音波洗浄機であって、洗浄槽の側面部には、洗浄槽の外壁面及び貯液部の内壁面に開口部を有する貫通孔が設けられ、貫通孔には、フロントマスが挿入され、フロントマスの先端面の上方を覆うようにカバーが設置され、カバーは、少なくとも上方に移動可能である。【選択図】図２Ｂ
