Abstract: In an embodiment, a coil component includes: a core 10; a coil conductor 40 having a spiral part 42 placed inside the core 10, and a lead part 48 which is led out from the spiral part 42 to the principal outer surface, constituting the bottom face 28, of the core 10, and which includes an end part 46 that serves as an external terminal 49; an insulated terminal 60 electrically insulated from the coil conductor 40, which is fitted onto and bonded to the core 10, and which has a bottom part 64 positioned on the bottom face 28, a top part 62 positioned on the top face 26, and a side part 66 coupling the bottom part 64 and the top part 62, where the top part 62 and side part 66 have an opening 68 in which an adhesive 82 is filled.

Abstract: 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.
