Abstract
PURPOSE:To obtain easily a long-life reproduced stylus which when used, never causes the breakaway, etc., of an electrode, by forming a conductive layer in a desired electrode shape on the surface of the reproduced stylus body where the electrode is expected to be formed, by irradiation with laser beams, etc. CONSTITUTION:A reproduced stylus body S made of diamond is arranged in the core tube 1, etc., of an electric furnace and placed under vacuum containing a trace of oxygen or in the atmosphere of inert gas containing a trace of oxygen. The reproduced stylus body S is heated by conducting electric current to a heater 2 to irradiate a surface A, where an electrode is expected to be formed, with a laser beam or an electron beam 3 through a deflector 4. Thus, the electrode is formed in a desired shape and desired size by using a conductive layer of carbon contained in the diamond.
