To provide a highly reliable short and small dust inductor for a large current in which the man-hours for welding is not needed since a coil and terminals are integrally formed without a limit to the terminal size, and damages do not occur in the cross section of a pattern line since the line is not made by pressing and extending a wire rod, which makes the terminal size large and a connection with an external circuit simple and steady.
The dust inductor is formed of a punched conductive metal plate, and has broad terminals integrally formed of the same material at both the ends of a narrow edgewise vertical winding coil. The vertical winding coil is buried in a mixture of metallic magnetic powder and a binder, and is pressure-formed. Also, a method for manufacturing the dust inductor is provided.
