摘要： In a coil component and a method for manufacturing the same, a winding part of a coil is grown by plating so as to extend between resin walls of a resin body provided before the coil is grown by plating. The resin wall is interposed between adjacent turns of the winding part of the coil during the plating growth, and therefore contact between adjacent turns of the winding part of the coil cannot occur.

摘要： In a coil component 1 and a method for manufacturing the same, a winding part of a coil is grown by plating so as to extend between resin walls of a resin body provided before the coil is grown by plating. The resin wall is interposed between adjacent turns of the winding part of the coil during the plating growth, and therefore contact between adjacent turns of the winding part of the coil cannot occur.

摘要： 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.
