PROBLEM TO BE SOLVED: To maintain the operation of circuit components and electronic components satisfactorily by reducing leakage flux of a chip inductor for surface mounting on a wiring board or for built in a wiring board, thereby reducing the impact of noise due to leakage flux on other circuit components and electronic components mounted on a wiring board.SOLUTION: The chip inductor for surface mounting on a wiring board or for built in a wiring board comprises: an internal conductor that makes up a coil 12 embedded in a magnetic material layer 11; a pair of electrodes 13 disposed at positions intersecting a surface of the magnetic material layer including the internal conductor, and connected electrically with one and the other ends of the internal conductor; and an electromagnetic wave noise absorption layer 14 placed on a surface of the magnetic material layer parallel with the surface including the internal conductor. |
