Abstract
In a common mode choke coil, electrodes of input/output terminals are located on a bottom surface of a bottom layer. First linear conductors and second linear conductors are located on base material layers. A primary coil includes the first linear conductors and via hole conductors. A secondary coil includes the second linear conductors and via hole conductors. In a plan view as seen from a direction of winding axes of the primary coil and the secondary coil, as for a plurality of first linear conductors and second linear conductors which are adjacent in a plan direction, there are provided a first region in which the second linear conductors are located between the first linear conductors, and a second region in which the first conductors are located between the second linear conductors.
