Abstract:
1. A method of winding a lead wire on a multi-winding electronic component that includes a winding core, collars at both ends of the winding core, electrodes on the collars at first and second sides of the winding core and a lead wire wound around the winding core, the method comprising: winding the lead wire around the winding core from the first side towards the second side to form a lower winding part; forming an upper winding part in which the lead wire is wound over the lower winding part in a direction from the second side to the first side by a number of turns that is smaller than a total number of turns of the lead wire in the lower winding part; folding back the lead wire at a predetermined folding-back position toward the second side and winding the lead wire over the upper winding part; and catching the lead wire folded back at the folding-back position at a bottom part of the collar on which one of the electrodes is formed on the winding core to form a final terminal part.
