PROBLEM TO BE SOLVED: To provide a reactor which achieves improvement of heat radiation performance from a core surface.SOLUTION: A reactor 1 includes: a coil 2 which generates magnetic flux by energization; a core 3 which is formed by a magnetic powder mixing resin made by mixing magnetic powder in a resin, the core 3 in which the coil 2 is buried; and a case 4 which houses the coil 2 and the core 3. A core surface 33 of the core 3 has a magnetic powder exposed surface 34 in which the magnetic powder is exposed from the resin. The magnetic powder exposed surface 34 has an irregular shape formed by the magnetic powder being exposed from the resin. |
