Claim Text:
1. A common mode choke coil comprising: a laminated body including a plurality of base material layers laminated on each other; a plurality of first linear conductors respectively provided on surfaces of the plurality of base material layers; a plurality of second linear conductors respectively provided on the surfaces of the plurality of base material layers; a primary coil including the plurality of first linear conductors that are spirally wound and connected; a secondary coil including the plurality of second linear conductors that are spirally wound and connected and magnetically coupled to the primary coil; a first region in which the plurality of second linear conductors adjacent to each other are located between the first linear conductors as seen in a plan view from a direction of winding axes of the primary coil and the secondary coil; and a second region in which the plurality of first linear conductors adjacent to each other are located between the second linear conductors as seen in the plan view from the direction of winding axes of the primary coil and the secondary coil; wherein the first linear conductor and the second linear conductor are not superimposed as seen in the plan view from the direction of the winding axes of the primary coil and the secondary coil in the first region and the second region.
