PROBLEM TO BE SOLVED: To provide a knurling surface reprocessing method of an ultrasonic welding tool which can regenerate a knurling surface of the adhered ultrasonic welding tool in a short time and can reduce a regeneration cost.SOLUTION: The knurling surface 9 which is adhered by using a technique such as brush lap, Aerolap (R), and shot blast is processed with respect to the knurling surface 9 which is adhered by repeatedly performing ultrasonic joining, and an adhered matter 12 is removed from the knurling surface 9. A friction coefficient of the upper surface 8a of a protrusion is set larger than friction coefficients of the inclined surface 8b of the protrusion and a groove 10 by plane-grinding the flat surface of the tip of the protrusion. By this, a time and labor for reforming the knurling surface 9 can be saved by completely grinding the worn knurling surface once and forming it into a flat shape.
