PROBLEM TO BE SOLVED: To perform favorable welding by precisely managing a condition of correctly performing predetermined pressing.SOLUTION: An ultrasonic welding device which performs ultrasonic welding by pressing a tool horn 44 attached to an ultrasonic sliding unit 40 slidable relative to a body frame 10 against a workpiece includes a first linear scale 50 measuring a moving amount of the tool horn 44, a compression spring pressing the ultrasonic sliding unit, a driving means 28 compressing the compression spring, a second linear scale 51 measuring a compressed amount of the compression spring, and a load cell 45 measuring a pressing force by the compression spring. When compressing the compression spring by driving the driving means 28, the pressing force by the compression spring measured by the load cell 45, the moving amount of the tool horn measured by the first linear scale 50, and the compressed amount of the compression spring measured by the second linear scale 51 are fed back to the driving means 28 and controlled to perform ultrasonic welding while imparting an optional pressing force to the workpiece.
