Abstract
A chip-like LC filter which comprises a cylindrical magnetic element having a through hole. A cylindrical capacitor element has a through hole and terminal electrodes formed on inner and outer peripheral surfaces thereof. A central conductor is inserted in the through holes of the magnetic element and the capacitor element, which through holes are aligned along an axial direction. The terminal electrode on the inner peripheral side of the capacitor element is electrically connected with the central conductor. Cap-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. The central conductor is obtained by cylindrically rolling a metal plate, so that a portion located on the outer periphery of the rolled metal plate defines an elastic contact portion which elastically comes into pressure contact with the terminal electrode on the inner peripheral surface of the capacitor element.
