ABSTRACT:
In an inductor having a core and first and second coils wound upon the core, the wire of the first coil and the wire of the second coil lie are wound so as to lie parallel to each other and contact the core. The winding starting position of the first coil is made to coincide with the winding starting position of the second coil along the axial direction of the core and is offset from the winding starting position of the second coil along the winding direction of the core. As a result, the area factor of the coils in the winding area of the inductor can be improved and the size of the inductor reduced.
