Abstract

PURPOSE:To enable cooling even when much heat is generated with a high electric current supplied to a metal core wire by forming a hollow metal core wire. CONSTITUTION:A hollow passage is formed on a metal core wire 1 within a metal sheath material 3. In this case, the inside of the hollow metal core wire 1 such as iron, nickel, stainless, and copper, etc., is filled with a low- temperature melting material 2 melting at a comparatively low temperature such as sodium nitrate (NaNO3) and potassium nitrate (KNO3) lead Pb, etc., and the diameter of the hollow metal core wire 1 is reduced to the outer diameter of a target. Moreover the hollow metal core wire 1 is housed within the metal sheath material 3 such as stainless and copper, etc., with an inorganic insulation material 4 such as alumina (Al2O3) and magnesia (MgO), etc., interposed, and the diameter of the metal sheath material 3 is reduced with a die, etc., to be finished to a target outer diameter. Then the low temperature melting material 2 packed within the hollow metal core wire 1 is pressurized from one end and heated to be taken out, and the inside hollow metal core wire 1 is washed with water, etc. This enables cooling even much heat is generated in the metal core wire 1.
