PURPOSE:To achieve excellent reproduction without any influence of some abrasion of a reproducing stylus tip and unnecessary matter on an information disk, by forming both side edges of an electrode on the electrode-formed surface of a reproducing stylus in parallel or at a small opening angle near the tip part of the stylus. CONSTITUTION:At the tip part of a reproducing stylus body 8 made of diamond, etc., a sliding contact surface 12 is formed, and an electrode-formed surface 10 having an adhered electrode 9 is formed succeeding to the surface 12. The electrode-formed surface 10, a successive connection part 13 between the surface 10 and the sliding surface 12 is regulated by a couple of side surfaces 10a and 10b formed nearly in parallel, and the electrode has a couple of side edges set in parallel or at a small opening angle at the stylus tip part. |
