Claims

[Scope of utility model registration request]

First and second flanges are formed at each end of a winding core that holds a coil winding, respectively, to constitute a core, and a pair of external lead electrodes are provided on an outwardly facing main surface of the first flange. A lead wire serving as each end of the coil winding is electrically connected to each external lead electrode, and a planar lead wire facing each other with the winding core sandwiched between the first flange is electrically connected to each external lead electrode. In the chip coil, a pair of side surfaces are formed, and each of the external extraction electrodes extends to each of the side surfaces and forms a side extension thereto. A chip coil, characterized in that the chip coil is formed on at least a part of the side surface excluding the central part.
