Abstract

PURPOSE: To obtain a large DC superposition-resistant amount and resistance to a high temperature by a method wherein a conductor having external electrodes at both ends and a magnetic substance composed of a magnetic metal powder and a powder bonding agent are filled and molded collectively by using a method of an injection, a press or the like in such a way that filling rate of the metal magnetic powder is 50vol.% or higher.
CONSTITUTION: A conductor 2 to which electrodes 1a, 1b have been connected electrically at its both ends is placed on a metal mold 3 for molding use; after that, a magnetic substance 4 composed of a magnetic metal powder and a powder bonding agent is filled, molded and solidified by using a method of injection, a press or the like in such a way that a filling rate of the magnetic metal powder is 50vol.% or higher; after that, the metal mold is detached; an inductor is obtained. An outer-face coating operation can be executed on the inductor excluding an external electrode part. At the inductor, a saturation flux density of the magnetic substance 4 is high and a saturation operation at a magnetic field by an electric current is slow. Thereby, the inductor whose DC superposition-resistant amount is large can be obtained; it is possible to obtain the inductor which is resistant to a high temperature, which is of a closed magnetic circuit type having an effective permeability sufficiently effective in shielding a noise, which has a sufficient inductance in high-frequency band and which complies with a wide band.
