This ultrasonic welding device forms welds on a continuously conveyed sheet member by applying ultrasonic vibration thereto. This ultrasonic welding device is characterized by being provided with: a rotating drum which conveys the sheet member by winding the same on the outer peripheral surface thereof and rotating; an ultrasonic horn which generates ultrasonic vibration; an anvil which, together with the ultrasonic horn, clamps the sheet member in the thickness direction when the ultrasonic horn generates ultrasonic vibration towards said sheet member wound on the rotating drum; a first drive source which rotates the rotating drum; a second drive source which moves the ultrasonic horn and/or the anvil along the direction of the rotational axis of the rotating drum; and a control unit which independently controls the first drive source and the second drive source. |
