PROBLEM TO BE SOLVED: To provide a reactor wherein noises due to movement of a part of a core are reduced. SOLUTION: The reactor 621 is provided with a core 30 and a coil 40. The core 30 includes three linear parts 31 to 33 and three curved parts 34 to 36. The curved parts 34 to 36 are arranged between the linear parts 31 and 32, the linear parts 32 and 33, and the linear parts 33 and 31, respectively. The linear part 31 is provided with gaps 37 and 38, the linear part 32 is provided with gaps 39 and 41, and the linear part 33 is provided with gaps 42 and 43. The core 40 is wound around the linear parts 31 to 33 in series. When a current is applied in the coil 40, a magnetic flux is generated in the core 30, and the magnetic flux circulates therein in the directions shown by arrows 44 to 46. Then, the curved parts 34 to 36 scatter an attraction force generated in the core 30 in the three directions 44 to 46. COPYRIGHT: (C)2005,JPO&NCIPI
