INDUCTOR

To provide an inductor which enhances contact between an internal coil and an external electrode to secure reliability of the inductor.SOLUTION: An inductor according to one example of the invention includes: a body including an internal coil having first and second end parts and a sealing material for sealing the internal coil and including magnetic particles; and first and second external electrodes electrically connected to the internal coil on an external surface of the body. A first metallic extension part which directly contacts with the first end part of the internal coil and covers the first end part is disposed between the body and the first external electrode. A second metallic extension part which directly contacts with the second end part of the internal coil and covers the second end part is disposed between the body and the second external electrode. A first connection layer and a second connection layer, formed by multiple layers, are respectively disposed between the first metallic extension part and the first external electrode and between the second metallic extension part and the second external electrode. Each layer of the first and second connection layers includes an intermetallic compound.SELECTED DRAWING: Figure 2 【課題】内部コイルと外部電極との接触性を強化してインダクターの信頼性を確保するインダクターを提供する。【解決手段】本発明の一例によるインダクターは、第１及び第２端部を有する内部コイルと、上記内部コイルを封止し、磁性粒子を含む封止材と、を含む本体と、上記本体の外部面上において上記内部コイルと電気的に連結される第１及び第２外部電極と、を含む。上記本体と上記第１外部電極との間には、上記内部コイルの上記第１端部と直接接触し、上記第１端部を覆う第１金属拡張部が配置され、上記本体と上記第２外部電極との間には、上記内部コイルの上記第２端部と直接接触し、上記第２端部を覆う第２金属拡張部が配置される。上記第１及び第２金属拡張部と上記第１及び第２外部電極との間には複数の層で構成される第１及び第２連結層がそれぞれ介在され、上記第１及び第２連結層の各層は金属間化合物を含む。【選択図】図２
