PROBLEM TO BE SOLVED: To improve a signal pass characteristic by lowering a low frequency impedance and reduce noise as before by maintaining an elevated high frequency impedance.SOLUTION: A coil component 1 comprises: a base 10 made of a magnetic substance; a coil conductor 12 disposed inside the base 10; a pair of terminal electrodes 11a, 11b disposed on a surface of the base 10 and electrically connected to both end portions of the coil conductor 12; and at least one closed loop conductor 13 disposed inside the base 10 and magnetically coupled to the coil conductor 12. The closed loop conductor 13 is disposed inward of an outer periphery of the coil conductor 12, and the closed loop conductor 13 has a loop size equal to or smaller than that of the coil conductor 12. |
