PROBLEM TO BE SOLVED: To provide a magnetic core structure which allows for reduction of leakage magnetic flux, and inexpensive production.SOLUTION: In a magnetic core structure 10 where a pair of magnetic cores 11, including a middle leg 12 around which a winding 20 is wound, and formed in E-shape in the side view, are arranged oppositely, the pair of magnetic cores include a base 13, a plurality of middle legs 12 standing in the longitudinal direction of the base 13, and a planar outside leg 14 standing along the opposite side of the base 13 in the longitudinal direction so as to cover each middle leg 12. For example, a slit-like high magnetic resistance region 15 is formed in the base 13, so that a magnetic flux generated in one middle leg 12a, around which a winding 20a is wound, does not interlink a winding 20b wound around other middle leg 12b.SELECTED DRAWING: Figure 3 |
