Inductive device and manufacturing method thereof

A manufacturing method of an inductive device, comprising:

• providing a magnetic base having an assembling surface, wherein an arrangement region is defined on the assembling surface;
• assembling a coil structure to the magnetic base, wherein the coil structure includes a coil body, a first extending section, and a second extending section, the coil body has a though hole corresponding in position to the arrangement region, the first extending section includes a first terminal portion, the second extending section includes a second terminal portion, the first and second extending sections both extend from the coil body toward the magnetic base and are wound on the magnetic base, and the first terminal portion and the second terminal portion are both located at a bottom surface of the magnetic base;
• and
• forming a package structure to cover the magnetic base and the coil structure, wherein the package structure includes a magnetic molding main body, and a portion of the magnetic molding main body fills into the through hole of the coil body and is connected to the magnetic base.
