<p>PROBLEM TO BE SOLVED: To provide a coil component having a planar coil for suppressing a parasitic capacitance generated between planar coils placed on front and rear faces of a substrate and each having at least one turn, and for suppressing a high-frequency noise.SOLUTION: Each planar coil is arranged so as to be floated by using a plurality of projection parts to a substrate to provide an air gap. In addition, a distance between lands corresponding to the projections on front and rear faces of the substrate is set to be longer by detour by means of a slit and notch, and thereby, a parasitic capacitance between the planar coils is suppressed, and a high-frequency noise can be suppressed.</p> |
