COIL COMPONENT AND METHOD OF MANUFACTURING THE SAME

摘要

In an embodiment, an air-core coil 50 includes a winding part 54 formed by winding a coated conductive wire 52, wherein a pair of leader parts 56 and 58 is interposed between a second core 20 and a first core 40 which contain metal magnetic grains. A first gap 72 is provided between a principle face 50A of one end portion of the winding part 54 in the direction of a winding core axis of the winding part 54 and the first core member 40. A second gap 70 is provided between a principle face 50B of the other end portion and the second core member 20. The coil component is a small and high-performance coil component with a high dielectric withstanding voltage.
