PROBLEM TO BE SOLVED: To provide a reactor having an excellent heat dissipating property regarding the reactor having a coil, a core filled on the inside and outer periphery of the coil and a case housing the coil and the core inside. SOLUTION: The reactor 1 has the coils 2 generating magnetic flux by electric conduction, the core 3 formed with magnetic-powder mixed resin filled on the inside and outer peripheries of the coils 2 and the case 4 housing the coils 2 and the core 3 inside. The case 4 is composed of a vessel section 40 with an opening section 43 and a cover section 5 closing the opening section 43 of the vessel section 40. The cover section 5 has internal fins 51 projected to the inside of the case 4. At least some of the internal fins 51 are embedded into the core 3. COPYRIGHT: (C)2008,JPO&INPIT
