In the above continuous vacuum degassing apparatus 21, the molten copper continuously supplied into the receiving chamber 2 from a molten copper inlet 4 is raised into the riser tube 8 and flowed in the connecting chamber 8 together with inert gas introduced from a blowing hole 11 at the intermediate position. At there, the degassing of the molten copper is executed and also the necessary additive is mixed from an additive charging hole 16. After that, the degassed molten copper is descended to the discharging chamber 3 through the downtake tube 9 and introduced out from a molten steel outlet 6. The inner diameter of the above downtake tube 9 is desirable to be more than 1.5 times the inside diameter of the riser tube 8. Further, the molten copper is desirably stirred by arranging an electromagnetic coil to each of the riser tube 8, downtake tube 9 and the connecting chamber 10.
