An ultrasonic processing system adapted to subject a web running in a machine direction to ultrasonic processing includes a first mechanical element defined by one of an ultrasonic horn and an anvil and a second mechanical element defined by a remainder. The web placed on an outer peripheral surface of a rotary drum moves conforming to the drum in a machine direction. The first mechanical element is provided on the inner side of the drum and the second mechanical element is provided on the outer side of the drum. The first and second mechanical elements repeat a step of forward movement and a step of backward movement in a direction intersecting the machine direction across the web. In both steps, the first and second mechanical elements come in close contact with each other by the intermediary of the web and thereby subject the web to the ultrasonic processing.
