Abstract
A thin film inductor is provided. The thin film inductor includes a first coil assembly, a first magnetic layer, and a second magnetic layer. The first coil assembly includes a first substrate and two first electrically conductive circuits respectively arranged on two surfaces of the first substrate that are opposite to each other. The first magnetic layer and the second magnetic layer are respectively arranged on the two surfaces of the first substrate that are opposite to each other, and the two first electrically conductive circuits are respectively embedded in the first magnetic layer and the second magnetic layer. The first substrate has a first non-circuit layout, and the first electrically conductive circuit is arranged around the first non-circuit layout. A ratio between an area of the first non-circuit layout and an area of the first substrate is 0.1 or more.
