ABSTRACT:
A wire-wound coil has a characteristic impedance that can be flexibly adjusted and can be prevented from varying undesirably. In the coil of the present invention, a primary wire part18A and a secondary wire part18B are wound around the surface of a core portion14so as to be separated from each other by a fixed distance. At the same time, at least one portion the secondary wire part18B in a prior turn section19X and at least one portion of the primary wire part18A in a subsequent turn section19Y are in close contact with each other, wherein the wire parts18A and18B are wound in different turns and are adjacent to each other on the same surface of the core portion14. A method for manufacturing the wire-wound coil is also disclosed.
