Abstract
A thin film inductor is disclosed, which includes a thin film magnetic core. The thin film magnetic core includes at least one magnetic thin film. In each magnetic thin film, at least one type-1 gap is provided. A length direction of the type-1 gap is parallel to a direction of hard magnetization of the magnetic thin film. If the thin film magnetic core comprises at least two magnetic thin films, the at least two magnetic thin films are laminated and overlap each other. A sum of widths of all type-1 gaps in each magnetic thin film is the same.
