ABSTRACT:
A common-mode choke coil includes a magnetic core, external electrodes, first and second wires, and a magnetic top. The magnetic core includes a winding core section and first and second flange sections. The external electrodes are provided on the first and second flange sections. The first wire is directly wound around the winding core section. The second wire is wound around the outside of the first wire. The first turn of the second wire is wound while being in contact with the first turn of the first wire and the first flange section.
