<p>PROBLEM TO BE SOLVED: To propose a structure which secures cooling performance of a coil and achieves small deterioration of inductance.SOLUTION: A reactor includes: a coil 30 having a rectangular projection shape when viewed in a winding axis direction; and a core 40 in which the coil 30 is embedded. The outer peripheral side of one long side in the rectangle of the coil 30 is exposed from the core 40 to contact with an inner peripheral surface of a side surface part 24 of the case 22. The structure secures cooling performance of the coil 30 and achieves small deterioration of inductance.</p> |
