A method for winding a lead wire on a multi-winding electronic component is provided. The method can prevent winding slack of the lead wire, a break of the lead wire, and/or a terminal disconnection failure. A lead wire is wound around a winding core by a certain number of turns to form at least one first layer. Next, the lead wire is folded back toward an electrode, is pulled toward the electrode at an end-of-winding side so as to be across the second layer. Then, the lead wire is caught at a bottom part of the collar to form a final terminal part for boding to the electrode.
