ABSTRACT:
A chip-like LC filter which comprises a cylindrical magnetic element having a through hole, a cylindrical capacitor element having a through hole and terminal electrodes formed on inner and outer peripheral surfaces thereof, and a central conductor inserted in the through holes of the magnetic element and the capacitor element aligned in the axial direction. The terminal electrode on the inner peripheral side of the capacitor element is electrically connected with the central conductor. Flange-shaped external terminal members are respectively provided on both end portions of the central conductor, so that the magnetic element and the capacitor element are located between the external terminal members.
