Abstract
An inductance component comprising a column-shaped magnetic material substrate, conductor layercovering ends and a peripheral surface of the substrate, coil portionhaving groove portionand wire conductor portionformed in the conductor layer covering the peripheral surface, electrode portionsincluding the conductor layer covering the ends of the substrate, and magnetic material portionmade of sintered magnetic material on the coil portion, wherein the conductor layer has a melting point higher than a sintering temperature of the sintered magnetic material. The manufacturing process comprises forming a substrate, forming a conductor layer, forming a coil portion, forming electrode portions at ends of the substrate, and forming a magnetic material portion of sintered magnetic material on the coil portion. The present invention provides an inductance component with high inductance, low magnetic flux leakage, and less undesirable magnetic effects on adjacent components.
