A thin film magnetic induction element includes a ferrite substrate, a coil provided across the ferrite substrate and including connection conductors and coil conductors, and terminals provided on perimeter portions of the substrate. Terminals capable of being adversely affected by an induced magnetic flux, such as a VDD terminal, a CGND terminal, an IN terminal, a PVDD terminal, a PGND terminal, an FB terminal, a CE terminal, and an AL terminal are arranged along the Y-direction of the substrate, in which the magnetic flux density is low. Terminals substantially incapable of being adversely affected by an induced magnetic flux are arranged along the X-direction of the substrate, in which the magnetic flux density is high. A micro electric power converter having the thin film magnetic induction element is less susceptible to circuit malfunctions.
