PROBLEM TO BE SOLVED: To provide a magnetic integrator of a planar inductor for a switched power converter comprising a filter means connected to a load for supplying zero ripple current. SOLUTION: A planar inductor 20 contains a magnetic core, comprising an E-type standardized magnetic-core section, and the outside leg part of the section is wound with first and second coils 21 and 22 which are magnetically combined for acquiring a leakage inductance, respectively. Thus, a common magnetic flux maintained by the coils 21 and 22 is guided in a ferromagnetic circuit formed with the outside leg part of a magnetic core, and the magnetic flux related to the leak inductance 21-2 is guided into a single outside leg part and a central leg part.
