PURPOSE: A manufacturing method of tungsten-copper composite powder and a manufacturing method of tungsten-copper composite using the same are provided to get grinding particle of uniform viscosity and uniform-size. CONSTITUTION: A manufacturing method of tungsten-copper composite powder is as follows. The solution consisting of solvent and dispersing agent is contained. The tungsten oxide powder and copper oxide powder are in thrown in the milling chamber(40) of the rotational basis wet bead milling containing solution by the constant rate. A mixing shaft(42) and the biz preparing within the milling chamber are rotated by using the motor. Solvent is circulated between the storage tank and the milling chamber in which solvent is saved and the slurry within the milling chamber is maintain made to the constant viscosity. The tungsten oxide and copper oxide powder are wetly crashed. The particle diameter of the copper oxide powder and tungsten oxide is measured at the particle size analyzer(70) preparing in the wet bead milling. The compound powder of the copper oxide and tungsten oxide is discharged from the milling chamber.
