Abstract

Provided are a coil component capable of contributing to improving productivity of a reactor, and a reactor exhibiting good productivity. A reactor 1A includes one coil 2 formed by spirally winding a wire 2w, and a magnetic core 3, which is disposed inside and outside the coil 2 and which forms a closed magnetic circuit. The magnetic core 3 includes an inner core portion 31 disposed inside the coil 2, and an outer core portion 32 disposed around the coil 2. The coil 2 and the inner core portion 31 constitute a coil component 2A held as an integral unit by a resin molded portion 20. A shape of the coil 2 is maintained by the resin molded portion 20. Since the coil component 2A includes a portion of the magnetic core 3, the number of components can be reduced, and the coil 2 and the inner core portion 31 can be easily placed into a case 4A when they are housed therein. The coil 2 is easier to handle because the coil shape is constantly maintained without expanding or contracting. Workability in assembly of the reactor 1A is improved by employing the coil component 2A.
