An inductor that includes a body having a magnetic portion containing a magnetic powder and a first resin; a coil that is encapsulated in the body and includes a winding portion formed by winding a conductor and a pair of lead-out portions that extend from the winding portion; and a pair of outer electrodes to which at least end portions of the lead-out portions are connected at surfaces of the body. The outer electrodes each includes an electrically conductive resin layer and a first cover layer arranged on the electrically conductive resin layer. The electrically conductive resin layers each contain an electrically conductive powder and a second resin and a plurality of electrically conductive metal portions composed of the same material as the first cover layers are contained inside the electrically conductive resin layers.

Inductor

An inductor includes a coil including a winding section in which a conductor having two opposite width surfaces is wound and extended sections extended from the winding section, an element body including a magnetic section in which the coil is embedded, the magnetic section including magnetic powder, and an outer electrode arranged on a surface of the element body and connected to the extended sections. The element body has first side surfaces opposite to each other. Each of the extended sections has a first zone approximately parallel with a corresponding one of the first side surfaces in one of the width surfaces of the conductor. The first zone is exposed from the first side surface and connected to the outer electrode. At least one of the extended sections includes a planar section meeting the first zone at an obtuse angle and extending to a tip of the extended section.

A surface-mount inductor including: a coil formed by winding insulated wire and bringing out lead ends therefrom; and a plurality of premolded bodies for accommodating the coil inside, thereby thermopressing to form, wherein a pair of metal terminals is embedded laterally on the outer surface of the surface-mount inductor, and the lead ends of the coil are brought out from the bottom surface of the surface-mount inductor and laterally laid on the outer surface of the metal terminals, as well as a method for manufacturing the same.
