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.

Abstract: An object is to provide a small and highly reliable inductor capable of handling a large current. The inductor includes: magnetic core formed by pressing a mixture of a powdered magnetic material and a binder; coil part disposed inside magnetic core; and external electrode formed by bending end portion of coil part protruding from magnetic core. Coil part and external electrode are made of a flat conductor, and a width of end portion of coil part protruding from magnetic core is less than an average width of coil part disposed inside magnetic core.
