Disclosed is a coil component having a magnetic core that is made of a magnetic material, and a terminal electrode portion and a coil portion that are made of a conductive material, wherein the coil components is configured such that the magnetic material and the conductive material contact with each other, and there is a relation of R<SUB>M</SUB>>=<SUP>20</SUP>Z<SUB>0 </SUB>when an insulation resistance of the magnetic core is R<SUB>M </SUB>(Q) and a peak impedance of the coil component is Z<SUB>0 </SUB>(Q).
