Coil component and method for producing magnetic powder-containing resin material used therefor

A coil component comprising:

• an element body including a coil conductor and a magnetic portion, the coil conductor including a wound conductor wire, and the magnetic portion containing metal magnetic material grains covered with an insulating coating, a resin, and insulator grains, the insulating coating having a uniform composition and being in contact with an entire outer surface of the metal magnetic material grains;
• and
• an external electrode electrically connected to an extended portion of the coil conductor and disposed on a surface of the element body,
• the insulator grains having a relative permeability lower than a relative permeability of the metal magnetic material grains, the insulator grains and the insulating coating being a compound whose main component is the same, and
• the magnetic portion includes an insulating material configured such that a portion of the insulating material is the insulating coating on the metal magnetic material grains and a remaining portion of the insulating material is the insulator grains distributed in the magnetic portion.
