The purpose of the present invention is to provide a thin film inductor element which utilizes a novel emergent electromagnetic field that does not have much difficulty in selecting materials, while not having high temperature dependence. A thin film inductor element that is characterized by comprising a multilayer film, in which a magnetic layer and a non-magnetic layer or an antiferromagnetic layer are stacked, and a pair of electrodes, while being also characterized in that: the magnetic layer and the non-magnetic layer or the antiferromagnetic layer are stretched in an arbitrary shape in a direction that is perpendicular to the stacking direction; the vertical orientation of the stacked layers is also arbitrary; the magnetic layer has a generally uniform magnetization structure; and the pair of electrodes are provided on both ends of the multilayer film in the stretched direction, while having an alternating current or a high frequency current applied thereto.
