Abstract: A coil component includes a coil portion and a main body. The coil portion has a central axis along a first direction and a ring-shaped conductor with two electric ends. The main body includes magnetic powder and a binder, and covers the ring-shaped conductor with a first surface and a second surface arranged side by side in the first direction. The main body has a first region formed of a first material and a second region formed of a second material. The first region includes the first surface and a central region, where the entire outer edge of the central region is in contact with the inner circumferential surface of the ring-shaped conductor, while the second region includes at least part of the second surface. The first material is different from the second material in at least one property in the magnetic powder, the binder, and another component, if any.
