<p>PROBLEM TO BE SOLVED: To provide a reactor in which heat dissipation properties are improved while inductance is maintained.SOLUTION: A reactor includes: a coil 1 toroidally wound so that the locus of a winding center forms a circle or an ellipse; composite magnetic materials 31, 32 mainly containing soft magnetic particles and a binder; and a conductive case having a housing part. The coil 1 is embedded in the composite magnetic material 32 disposed at the bottom of the housing part, and an end face 12 that is a surface of an end part along the central axis of the locus of a winding center of the coil 1 is in close approach with the internal surface of the housing part.</p> |
