ABSTRACT:
A feedthrough electronic device which has an electronic element with a feedthrough hole and a center conductor which penetrates the electronic element. The center conductor is composed of a lead line portion and a spring portion which protrudes from the lead line portion and contacts with an inner periphery of the electronic element with pressure. A wide portion for preventing deformation is provided at the spring portion. A ferrite bead, a doughnut-shaped capacitor or a tubular capacitor can be used as the electronic element which has a feedthrough hole. The lead line portion of the center conductor and the spring portion can be produced separately or integrally.
