Abstract
An object of the present invention is to provide a coil component in which leakage of magnetic flux from a magnetic gap is reduced. A coil component includes: a drum-shaped corehaving a winding core partwith a gap G formed therein and first and second flange partsand; a plate-like corefixed to the first and second flange partsand; and wires Wto Wwound around the winding core partand each having one end connected to a terminal electrode provided on the first flange partand the other end connected to a terminal electrode provided on the second flange part. According to the present invention, the gap G formed in the winding core partfunctions as a magnetic gap, and magnetic flux leaking from the magnetic gap is shielded by the plate-like core. Thus, even when the magnetic gap is provided to reduce a tolerance due to characteristic variation of a magnetic material, it is possible to solve the problem that other electronic components are affected by the leakage magnetic flux.
