Abstract: An object is to obtain an inductor that has a low inductance and can withstand a large current. Inductor includes magnetic core obtained by mixing a powder magnetic material and a binder and compression-molding a mixture, and flat conductive wire embedded in magnetic core and extending linearly with an end portion protruding from an end surface of magnetic core. When viewed from a top surface, magnetic core includes central portion covering flat conductive wire, side surface portions provided on both sides of central portion, and tapered portions provided between central portion and side surface portions, and a thickness of side surface portions is thinner than a thickness of central portion.

Abstract: An object of the present disclosure is to achieve a small-sized inductor capable of handling a high current, and having a high coupling coefficient. Inductor includes magnetic core and coil element embedded in magnetic core. Coil element includes at least four flat coils, and first coil element, second coil element, third coil element, and fourth coil element are provided in an overlapping manner. Ends of each coil element protrude from bottom surface, and are bent along bottom surface, to form external electrode. Ends of first coil element and ends of third coil element are bent toward first side surface. Ends of second coil element and ends of fourth coil element are bent toward second side surface.
