| description | PROBLEM TO BE SOLVED: To provide an inexpensive reactor that matches the size of an apparatus side demand. SOLUTION: The reactor includes a laminated E-type iron core 1 and a laminated I-type iron core 2, both of which are arranged to face each other, wherein: an air gap 5 for adjusting magnetic saturation characteristics is formed between a central magnetic leg 1a of the laminated E-type iron core 1 and the laminated I-type iron core 2 arranged opposite thereto; and a coil 3 is wound around the periphery of the central magnetic leg 1a through an insulating paper 4. The coil 3 is serially connected by using a coil 3a and a coil 3b, thereby reducing an unit cost of raw materials compared with the case of using a coil that makes single copper serve as a conductor, wherein copper and aluminum in which an enamel film is baked on the surface of the coil 3a and the coil 3b, respectively, serve as the conductor. A small core with a short magnetic path length can be used compared with the case of using the coil in which a single aluminum serves as the conductor, thereby matching the size of the apparatus side demand and achieving low cost.
