<p>This method for producing a copper alloy wire containing an active element includes: a molten-copper formation step of melting a raw copper material to form a molten copper; an active-element addition step of adding an active element to the molten copper; a holding step of holding the molten copper in a casting furnace; and a casting step of producing an ingot continuously by a casting die connected to the casting furnace, wherein the casting die is connected to a lower side of the casting furnace in a vertical direction through a heat insulation member, and in the casting step, a pressure is applied toward the inside of the casting die so as to supply the molten copper into the casting die, and the molten copper is cooled and solidified in the casting die.</p> |
