<p>Provided is an inductance element which is not interfered by peripheral circuits when mounted on a wiring board, by forming a closed magnetic path, and has a small reduction of an inductance value even when a direct current is superimposed, namely, has excellent direct current superimposition characteristics. The temperature coefficient of the magnetic permeability of a ferrite sintered body which constitutes a magnetic core (5) is permitted to be positive. The temperature coefficient of the magnetic permeability of a soft magnetic resin constituting an external (8) formed to cover a coil (7) and to fill a space between flange sections (3, 4) of the magnetic core (5) is permitted to be -30ppm/°C Or less, preferably -1,000ppm/°C or less.</p> |
