Abstract
An inductance element comprises conductive paths of copper and a spool member arranged on a substrate, and insulated winding formed by a fine copper wire whose surface is coated with an insulating film of urethane etc. is wound around the spool member so that both end portions thereof are subjected to ultrasonic vibration by an ultrasonic bonding apparatus to be connected to the conductive paths by ultrasonic bonding. Thus, the end portions of the winding can be processed by local heating with application of ultrasonic vibration, whereby the coil needs not be entirely heated and an inductance element can be readily implemented directly on the substrate.
