Abstract

PURPOSE:To improve the workability for welding a small-sized article by forming a parallel gap electrode used for bonding a metallic wire of conical electrodes integrated in insulation with a basic cylinder. CONSTITUTION:A basic cylinder 8 becoming a holder having a feeding hole 9 for passing a bonding wire is made of hard insulating material or metallic material, and a conical parallel gap electrode 10 becoming a capillary mounted integrally with the lower portion of the cylinder 8 is made of metallic material such as Mo or the like. In this configuration the electrode 10 is made of two portions 10a, 10b, a tapered hole 13 for receiving a wire ball is formed at the end thereof, the insulating material 12 such as ethylene tetrafluoride or glass is coated on the seam between the portions 10a and 10b and the tapered inner surface. Thus, an electric current is flowed between the positions 10a and 10b to create a ball in the hole 13, molten solder is urged to the substrate to weld it without directivity.
