Abstract

An inductor and a method for manufacturing the same are provided. The inductor includes a magnetic packaging structure, a coil embedded in the magnetic packaging structure, two extending wires connected to two ends of the coil and two encapsulation materials. The magnetic packaging structure includes a surface and two cavities on the surface. Each extending wire includes a bending part, a pin part and a fixture part connected to one another in sequence. The bending part extends to the surface from the coil and penetrates through the surface to be exposed to the outside of the magnetic packaging structure. The pin part on the surface extends to one of the cavities from the bending part. The fixture part extends to a bottom surface along with a side wall of the cavities. The encapsulation materials are disposed inside the cavities and cover the fixture part.
