PROBLEM TO BE SOLVED: To provide a reactor which effectively reduces leakage of magnetic flux occurring when a coil is excited and is excellent in productivity.SOLUTION: A reactor 1 includes: one cylindrical coil 2 formed by spirally winding a coil 2w; and a magnetic core 3 disposed at the interior and the exterior of the coil 2 and forming a closed path. An outer core part 32 provided at the outer peripheral side of the coil 2, from among the magnetic core 3, is formed by a composite material including magnetic material powder and a resin. The reactor 1 includes: a bottom part shielding plate 40 fixed to a bottom part of the outer core part 32; a side part shielding plate 41s fixed to a side surface; and an end part shielding plate 41e fixed to an end surface; and a top part shielding plate 42 fixed to a top plate. Each shielding plate shields the leakage of magnetic flux occurring when the coil 2 is excited to the exterior of the outer core part 32. |
