Abstract: A coil device includes an inner core having a winding core and a pair of flanges, a wire, an outer core arranged outside the inner core, a first terminal with a first wirebound having a first wirebound bottom arranged axially on a core end surface of the outer core and connected to a first end of the wire, and a second terminal with a second wirebound having a second wirebound bottom arranged on the core end surface and connected to a second end of the wire. The first wirebound has a first wire fixing portion bending from the first wirebound bottom toward a first rotating direction and fixing the first end. The second wirebound has a second wire fixing portion bending from the second wirebound bottom toward the same rotating direction as the first rotating direction and fixing the second end.
