<p>PROBLEM TO BE SOLVED: To provide a reactor with an excellent heat radiation property of a coil and capable of restraining propagation of vibration from the coil to a case.SOLUTION: A reactor 1 has a core 2 made of magnetic powder mixed resin, a coil 3 one part of which is embedded in the core 2 and around wich a conductor wire is spirally wound, and a case 4 for housing the core 2 and the coil 3 inside. The core 2 has a magnetic path formation part 21 for forming an annular magnetic path including an inner peripheral side and an outer peripheral side of the coil 3. The coil 3 has an exposure part 31 exposed from the core 2 and the case 4 on one part of an outer periphery 301. Also, an inner periphery 302 of the coil 3, an outer periphery 301 except for the exposure part 31, and a pair of end faces 303, 304 in an axial direction are covered by a bobbin 5 made of an insulation material. A vibration absorbing part 14 for absorbing vibration is formed between at least one of a pair of the end faces 303, 304 in the axial direction of the coil 3 and the bobbin 5.</p> |
