description | To provide an inductor capable of improving bond strength of a core where a coil is arranged and a magnetic substance, without compressing the magnetic substance with a high pressure.SOLUTION: An inductor 1 includes a body 16 and an external electrode formed on a surface of the body. The body 16 includes a core 4 having a base part 6 and a column 8 placed on a top face of the base part, a coil 10 having a wound part formed by winding a conductor around the column 8, and a pair of lead-out parts led-out from the wound part and connected with the external electrode, and a magnetic substance 2 including the coil 10 and at least a part of the core, and containing magnetic powder and resin. The base part 6 has an undersurface, i.e., a surface at an opposite side to the top face, multiple lateral faces 6c, 6d connecting the top face and the undersurface, and a notched surface connecting the top face and the undersurface, and placed between the lateral faces. The lead-out parts are led out from an upper surface side to a lower surface side of the base part, along a notched surface, and the notched surface is covered with the magnetic substance 2.SELECTED DRAWING: Figure 1A
【課題】磁性体を高圧で圧縮することなく、コイルが配置されたコアと磁性体との接合強度を高めることができるインダクタを提供する。【解決手段】インダクタ1は、素体16と素体の表面に形成された外部電極を備える。素体16は、ベース部6及びベース部の上面に配置された柱状部8を有するコア4と、柱状部8に導線を巻回して形成された巻回部及び巻回部から引き出され、外部電極に接続される一対の引き出し部を有するコイル10と、コイル10とコアの少なくとも一部を内包し、磁性粉と樹脂とを含む磁性体2と、を備える。ベース部6は、上面の反対側の面である下面、上面及び下面を繋ぐ複数の側面6c、6d及び上面及び下面を繋ぎ、側面の間に配置された切り欠き面を有する。引き出し部は、切り欠き面に沿って、ベース部の上面側から下面側に引き出され、切り欠き面は、磁性体2で覆われている。【選択図】図1A |
