Abstract
In a coil component (planar coil element), at least part of a third metal magnetic powder constituting a metal magnetic powder and having a minimum average grain diameter is uncoated, which suppresses a reduction in magnetic permeability. On the other hand, the remaining metal powders are coated with glass, which improves the insulating properties of a metal magnetic powder-containing resin and reduces core loss.
