Abstract: An inductor device has a core base, and an inductor structure including a first conductive pattern formed on a first surface side of the core base, a second conductive pattern formed on a second surface side of the core base on the opposite side with respect to the first surface side of the core base, and a through-hole conductor formed through the core base such that the through-hole conductor is connecting the first conductive pattern and the second conductive pattern. The core base includes a magnetic material layer including a magnetic material, and the magnetic material layer of the core base is positioned adjacent to at least a portion of the periphery of the inductor structure.
