PROBLEM TO BE SOLVED: To provide an ultrasonic continuous pickling method by which a pickling efficiency is made stable by reducing the bubble concentration of hydrogen generated by the dissolution of a strip in a pickling liquid, thereby increasing the intensity of ultrasonic waves applied to the strip by an ultrasonic vibrator. SOLUTION: The ultrasonic continuous pickling method where a running strip is dipped into a continuous pickling tank, and is pickled while applying ultrasonic waves thereto, the inside of the continuous pickling tank is provided with a mesh-like sieve, and bubbles generated by the pickling are removed.
