    Abstract: 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.
