发明名称 COIL COMPONENT AND POWER-SUPPLY DEVICE PROVIDED THEREWITH
摘要 The coil component includes a magnetic core 130 and conductors 210 and 220. The magnetic core 130 includes through-holes that are made by grooves 111 and 112. The conductors 210 and 220 are provided in the grooves 111 and 112, respectively. The magnetic core 130 includes a nonmagnetic portion in which the grooves 111 and 112 are communicated, and a distance between the conductors 210 and 220 through the nonmagnetic portion is shorter than a distance between the conductors 210 and 220 in surfaces 110c and 110d in which the conductors 210 and 220 are exposed. Therefore, necessity to provide a large cavity in the magnetic core is eliminated, and a risk of the short circuit between terminal electrodes exposed in the surfaces 110c and 110d is also eliminated.
