An inductance component comprising a column-shaped magnetic material substrate 21, conductor layer 24 covering ends and a peripheral surface of the substrate, coil portion 27 having groove portion 25 and wire conductor portion 26 formed in the conductor layer covering the peripheral surface, electrode portions 28 including the conductor layer covering the ends of the substrate, and magnetic material portion 31 made 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 bad magnetic effects to adjacent components.
