PURPOSE:To fit precisely a reproducing stylus body to a holder with excellent operativity, by forming an electrode surface for detecting variation in electrostatic capacity to one surface of the reproducing stylus body, and forming a step part which abuts on the fitting hole of the holder. CONSTITUTION:One surface of the reproducing stylus body is made into the electrode surface for detecting variation in electrostatic capacity and the step part which abuts on the attachment hole of the holder is formed. For example, the reproducing stylus attachment hole 8 which has a right or optional angle lengthwise is formed at one end part of the holder 7 made of thermoplastic resin. Then, the reproducing stylus body 9 made of a material with wear resistance entirely or as part of the tip part is provided with the step part which increases in sectional area lengthwise from an optional position to have a cyilindrical part at the upper part. The reproducing stylus body 9 is inserted into the attachment hole 8 until the step part end surface 10 contacts the upper end surface of the attachment hole 8 and then fixed with an adhesive; and the electrode surface 12 for detecting variation in electrostatic capacity is formed as one surface of the reproducing stylus body 9. |
