Summary:A choke coil having a sufficient noise eliminating effect against common mode and normal mode noises. The choke coil has a bobbin, a pair of windings wound around the bobbin, and magnetic cores inserted in a rectilinear body portion of the bobbin. The bobbin is constituted by a main body and a cap each of which incorporates a magnetic core. The upper half of those magnetic cores forms a closed magnetic circuit that extends around one of the windings while the lower half forms a closed magnetic circuit that extends around the winding.
