Inductor and electronic device including the same

An inductor comprising:

• a coil in which an electric current is configured to flow;
• and
• a core that the coil is wound around,
• wherein the core comprises a central portion that the coil is wound around;
• extension portions extending from opposite edges of the central portion according to a circulation path of magnetic flux generated by the electric current of the coil;
• and lateral portions extending from the extension portions along the circulation path of the magnetic flux and facing the central portion with the coil disposed there between, and
• the core is configured such that a vertical side which the magnetic flux passes through along the circulation path of the magnetic flux has a uniform area.

An electronic device comprising:

• a printed circuit board on which an electronic component configured to drive the electronic device is mounted;
• and
• an inductor mounted on the printed circuit board,
• wherein the inductor comprises a coil in which an electric current is configured to flow and a core that the coil is wound around,
• the core comprises a central portion that the coil is wound around, extension portions extending from opposite edges of the central portion according to a circulation path of magnetic flux generated by the electric current of the coil;
• and lateral portions extending from the extension portions along the circulation path of the magnetic flux and facing the central portion with the coil disposed there between, and
• a first height at a first position of the extension portions on the circulation path of the magnetic flux spaced away from the edges of the central portion by a first distance which is larger than a second height at a second position on the circulation path of the magnetic spaced away from the edges of the central portion by a second distance which is longer than the first distance.
