Abstract
An inductive device and a method of manufacturing the same are provided. The inductive device includes a magnetic base, a coil structure, and a package structure. The magnetic base includes a bottom plate, a core column, and a lateral wall defining a positioning trench. The coil structure includes a coil body, a first extending section, and a second extending section. The coil body disposed in the positioning trench surrounds the core column. The first extending section includes a first bent portion and a first terminal portion connected at a first connecting point. The second extending section includes a second bent portion and a second terminal portion connected at a second connecting point. A shortest distance between a first imaginary connection line defined between the first and second connecting points and a central axis of the core column is less than a minimum outer radius of the coil body.
