| 1. A coil component comprising:
a core comprising a coil winding portion having one axial end and another axial end, a first flange disposed on the one axial
end and defining a first end face of the core, and a second flange disposed on the another axial end and defining a second
end face of the core, the first flange having a bottom surface constituting the first end face and a peripheral surface extending
toward the second end face from a peripheral edge of the bottom surface, the bottom surface having a first side and a second
side opposing the first side, a first omitted side at a first end of the first side, and a second omitted side at one of a
first end and a second end of the second side, the first omitted side being configured as if a first corner located on a first
end of a first specific side of an imaginary quadrangle corresponding to the first side is chamfered or cut, and the second
omitted side being configured as if a second corner located on one of first end and second end of a second specific side of
the imaginary quadrangle corresponding to the second side is chamfered or cut, the peripheral surface having a first peripheral
surface extending from the first side, a second peripheral surface extending from the second side, a first omitted peripheral
surface extending from the first omitted side adjacent to the first peripheral surface, and a second omitted peripheral surface
extending from the second omitted side adjacent to the second peripheral surface;
a winding wound about the coil winding portion and having a first end and a second end; and
terminal electrodes disposed on the first flange and comprising a first terminal electrode and a second terminal electrode,
the first terminal electrode being disposed across the first omitted peripheral surface and a part of the bottom surface,
and the second terminal electrode being disposed across the second omitted peripheral surface and another part of the bottom
surface separated from the first terminal electrode, the first end of the winding being electrically connected to the first
terminal electrode at the first omitted peripheral surface and, a second end of the winding being electrically connected to
the second terminal electrode at the second omitted peripheral surface.
