The purpose of the present invention is to provide a manufacturing method of spherical titanium powder and the spherical titanium powder manufactured thereby. The provided manufacturing method of the spherical titanium powder according to the present invention for the purpose comprises: a step (step 1) of hydrogenating titanium scraps; a step (step 2) of manufacturing angled titanium hydride powder by pulverizing titanium hydrogenated in the step 1; a step (step 3) of manufacturing angled titanium powder by applying a vacuum heat treatment to the angled titanium hydride powder manufactured in the step 2 by pulverizing the hydrogenated titanium; and a step (step 4) of manufacturing the spherical titanium powder by applying a plasma treatment to the angled titanium powder manufactured in the step 3. In addition, the provided spherical titanium powder manufactured by the method according to the present invention for the purpose has a granularity of 5 to 100nm or 500 to 200μm. According to the present invention, through the plasma treatment, the angled titanium powder manufactured through an existing hydrogenation-dehydrogenation process (H-DH process) can be formed into spherical shapes to be used in metal injection molding; the particle size of the titanium powder can be reduced; and impurities can be removed from inside the titanium powder.
