PURPOSE: A manufacturing method of a natrium-sulfur battery is provided to form an entirely even junction layer and to produce a bonding interface with excellent fretting against melting sodium. CONSTITUTION: A manufacturing method of a natrium-sulfur battery has a process of welding metal to an insulator (20) insulating the anode and cathode of the natrium-sulfur battery. The soldering process of the metal comprises the steps of: producing paste (30) by mixing Al powder, Mg powder, Si powder, a binder and a solvent, coating the manufactured paste on the surface of the insulator, and paste the metal to the insulator by thermocompressing with the medium of the paste coated on the insulator. The paste includes the Mg powder of 0.5-1.5 weight%, and 5-15 weight% of the Si powder against the whole mixture.
