To provide an ultrasonic cutting device cutting the material to be cut using a long blade-like blade body.SOLUTION: An ultrasonic cutting device comprises: a linear blade body; a tension-imparting member; a fixing frame forming a fixed-end fixing one end of the blade body and a tension-imparting end supporting the blade body while freely imparting tension at the other end of the blade body by the tension-imparting member; tension-imparting means imparting the tension to the blade body by the above member at the tension-imparting end of the fixing frame; first fixing means fixing one end of the blade body to the fixed-end of the fixing frame; second fixing means fixing the other end of the blade body to the tension-imparting member of the fixing frame tension-imparting end; a horn; ultrasonic vibration means; and ultrasonic vibration control means. The cutting device is configured: to support both ends of the long blade-like blade body at the position of a flexible vibration knot of a blade body side face; to evenly generate the flexible vibration by a blade side face by dabbing the tip of the ultrasonic vibration horn at the middle position of the above flexible vibration in such a state as applying the tension to the blade body; and to cut the material to be cut by pushing the blade body thereto.SELECTED DRAWING: Figure 1 【課題】長刃状の刃体で被切断物を切断する超音波切断装置を提供する。【解決手段】直線的な刃体と、張力付与部材と、刃体の一端を固定する固定端および刃体の他端側で張力付与部材により張力付与自在に支持する張力付与端を形成した固定枠と、固定枠の張力付与端で、張力付与部材により刃体に張力を付与する張力付与手段と、刃体の一端を固定枠の固定端に固定する第一の固定手段と、刃体の他端を固定枠の張力付与端の張力付与部材に固定する第二の固定手段と、ホーンと、超音波振動手段と、超音波振動制御手段と、を有し、長刃状の刃体両端を刃体側面のたわみ振動の節の位置で支持し、刃体に張力をかけた状態で、刃体側面のたわみ振動の腹の位置に超音波振動するホーンの先端を当てて、刃体全体を一様に、刃体側面でたわみ振動させ、被切断物に刃体を押し当てて切断するように構成した。【選択図】図１
