1. A coil device comprising:
- an inner core having a winding core with column shape extending in an axial direction and a pair of flanges arranged on both sides of the winding core;
a wire having a winding portion winding around the winding core;
an outer core having a through hole inserted by the inner core and being arranged on an outer periphery of the inner core;
a first terminal portion provided with a first wirebound portion having a first wirebound bottom portion arranged on a core end surface of one of end surfaces of the outer core in the axial direction and connected to a first end of one of ends of the wire; and
a second terminal portion provided with a second wirebound portion having a second wirebound bottom portion arranged at a position rotated in a peripheral direction by a predetermined angle from the first wirebound bottom portion on the core end surface and connected to a second end of the other end of the wire,wherein the first wirebound portion is provided with a first wire fixing portion bending from the first wirebound bottom portion toward a first rotating direction as seen from a tip side of the first end and fixing the first end, andthe second wirebound portion is provided with a second wire fixing portion bending from the second wirebound bottom portion toward the same rotating direction as the first rotating direction as seen from a tip side of the second end and fixing the second end.

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.
