Abstract
An inductor includes: an inductive coil having a coil portion and two extension legs; a magnetic pillar including a pillar portion that is inserted into the coil portion and that has an upper end projecting upwardly from the inductive coil, and a flange portion radially projecting from the upper end of the pillar portion, the flange portion pressing against an upper end of the coil portion; and an embedding body in which the coil portion and the magnetic pillar are embedded, the extension legs being exposed from the embedding body.
Claims3
An inductor, comprising:
- an inductive coil having a coil portion and two extension legs;
- a magnetic pillar including a pillar portion that is inserted into said coil portion and that has an upper end projecting upwardly from said inductive coil, and a flange portion radially projecting from said upper end of said pillar portion, said flange portion pressing against an upper end of said coil portion;
- and
- an embedding body in which said coil portion and said magnetic pillar are embedded, said extension legs being exposed from said embedding body.

A method for making an inductor, comprising:
- forming a magnetic pillar having an upper end formed with a radially projecting flange;
- inserting the magnetic pillar into an inductive coil until the radially projecting flange presses against an upper end of the inductive coil;
- disposing the inductive coil together with the magnetic pillar in a mold;
- filling the mold with a magnetic powder;
- and
- compression molding the magnetic powder to form an embedding body in which the inductive coil and the magnetic pillar are embedded.
