Abstract: An inductor component includes coil portion that is formed by conducting wire being wounded, and has hollow portion in a winding axis direction, terminal electrodes that are made of metal plate, and serve as a pair of first terminal electrode and second terminal electrode connected to coil portion, and molded body that is made of a magnetic material of a soft magnetic powder and a resin, and has coil portion buried. The pair of terminal electrodes are disposed on the opposite side of each other through winding axis, the pair of terminal electrodes each have coil fixing portion that coil portion is fixed to, coil fixing portion integrally has erected portion adjacent to an inner periphery side of coil portion, and this erected portion has curved portion curved along the inner periphery side of coil portion when viewed from a winding axis direction.

Abstract: The present invention provides a coil component and a method for making the coil component that includes: a coil section having a through hole and composed of a plurality of ring sections formed of a metallic flat plate disposed in a plane, connected to each other at ring connecting sections, having slits formed by cutting part of the ring sections, and bent at the ring connecting sections and placed one on top of another, terminals connected to the coiled section, and a package member covering the coil section and projecting the terminals therefrom. With this structure, the coil component operates in a high-frequency region, ensuring an inductance and infinitesimal direct-current resistance while being adaptable to a large current, and can be miniaturized.

Abstract: A coil component includes a coil 2 having a through-hole 1, a magnetic core encapsulating the coil, and a terminal 4. The magnetic core includes a top portion 11 disposed at an upper part of the coil, a bottom portion 12 disposed at a lower part of the coil, and a middle portion 13. An outer layer thickness of the middle portion (W1) is less than a diameter of the through-hole, while the top portion and the bottom portion are higher in density than the middle portion. The configuration of the present invention provides a small size coil component with less occurrence of magnetic saturation to prevent lowering of inductance even with thin top 11 and bottom portions 11, 12. The coil component further has improved reliability.
