ELECTRODE AND ELECTRONIC COMPONENT PART USING THE SAME

PURPOSE:To prevent the crack of a sealing body, and to obtain high reliability by forming a header section by the machining of a plurality of headers. CONSTITUTION:In the first heater machining, a metallic wire 20 called a dumet wire in which the periphery of an electrode material core material 21 is coated with a copper layer is inserted into the hole of a die 14, and brought into contact with a jig 15. When the projecting end of the metallic wire 20 is stuck by a striking jig shown by the arrow A1, a header section 1 of a comparatively large diameter is formed, the inner side surface of the header section 1 is brought into contact with the end surface of the die 14, and a smooth surface is formed. The jig 15 is moved to the right side, the second header machining is executed by a jig as shown in the arrow A2, and a stepped section 19 of a diameter smaller than that of the header section 1 is shaped on the inner end side of the header section 1. Accordingly, the header section 1 is in contact with only the end surface of a sleeve by the inner end surface of the stepped section 19 when the electrode is assembled as a leadless diode.
