Abstract: Disclosed is an inductance part including a coiled conductor formed from a metal conductor, a magnetic body formed by pressure-molding a mixture of metal magnetic powder and bonding material in such a manner that the coiled conductor is embedded in the mixture, and a terminal derived from the coiled conductor. The coiled conductor is formed in a single layer with no insulating film on its surface. The metal magnetic powder of the magnetic body penetrates into the surface of the coiled conductor so as to make the filling factor of the metal magnetic powder in the magnetic body not less than 80% by volume.
