PURPOSE: To manufacture an active metallic hollow tubular body having a high melting point, which is difficult to manufacture, using a simple means.
CONSTITUTION: A melting base material 12 having a preliminarily controlled structure is melted in a water cooled copper crucible 3 without contact with the crucible, a dropping metal in the melted state is pulverized with an inert gas to be made to atomized powder. A core material 22 rotating around the axial line and moving in the axial direction is arranged below the atomized powder. When the liquid drop of the base material 12 is supplied downward, the base material 12 is rotated to make the melting state of the metal in the circumferential direction of the base material uniform. Then, the active metal having a high melting point is atomized to be made to semi-solidified state and is tubularly deposited on the circumference of the hollow core material 22.
