Abstract:
A method for manufacturing an electronic component comprising:preparing two cap-shaped terminals comprising iron or an alloy containing iron, a substantially cylindrical central conductor comprising copper or an alloy of copper and having substantially cylindrical open end faces, and an element having a through hole for receiving the central conductor; forming a nickel film at least on the inner face of each of the cap-shaped terminals; disposing the element on the central conductor while the central conductor is received in the through hole; putting each of said cap-shaped terminals on respective ends of the element so that the inner face of each of said cap-shaped terminals is allowed to butt against each of said substantially cylindrical end faces of the central conductor via the nickel film; and allowing a part of each of the cap-shaped terminals and the central conductors, and at least a part of the nickel film to melt by flowing electric currents through each of the cap-shaped terminals and the central conductor to generate heat based on contact resistance between each of the cap-shaped terminals and the central conductor, thereby joining each of the cap-shaped terminals to the central conductor such that a first alloy layer containing nickel, copper, and iron is formed at the cap-shaped terminal side of an interface between each of the cap-shaped terminals and the central conductor, and a second alloy layer containing nickel and copper is formed at the central conductor side of said interface; wherein the two cap-shaped terminals are joined to the central conductor via only both the first alloy layer and the second alloy layer.
