will melt and create holes, making it impossible to achieve the purpose of joining. Furthermore, if the applied strength of ultrasonic vibration is weak, non-welded portions will remain. Therefore, if the pressing force of the horn 4 is controlled in accordance with the feeding speed of the polymer films 5, 6, the welded portion will be constant and the polymer films 5, 6 will be properly joined.
