Abstract: An inductor includes a magnetic core obtained by pressure-molding a mixture of a magnetic material powder and a binding agent, and coil elements buried in the magnetic core. The coil elements include two tabular coils that are a first coil element and a second coil element provided overlappingly in stated order from a first side face side to a second side face side. End portions of the coil elements protrude from the bottom face and are bent along the bottom face to configure external electrodes. One of first external electrodes extends toward a first end face and an other one of the first external electrodes extends toward the second end face, and second external electrodes extend toward a second side face.

Abstract: An inductor includes: an exterior member having a bottom surface and a side surface; and an electric conductive member partially covered by the exterior member. The electric conductive member includes a coil portion covered by the exterior member; lead portions connected to both ends of the coil portion, extending toward the bottom surface, and covered by the exterior member; and terminal electrodes connected to the lead portions and exposed from the bottom surface. The side surface includes recesses recessed inward of the exterior member from the side surface and connected to the bottom surface. The terminal electrodes extend along the bottom surface toward the recesses, are bent from the bottom surface toward the recesses, and housed therein. At least a part of each lead portion is opposite to the recess. Each lead portion has a thickness smaller than a diameter or a thickness of a wire of the coil portion.
