PURPOSE:To make the read of signals sure and reduce the waste of mechanical works, by forming a wide part between the electrode part of a prescribed width for information signal detection and the signal taking-out part. CONSTITUTION:Electrode part 3A and signal taking-out part 13 are stuck and formed on plane electrode forming face 6 perliminarily as the conductive film having a continuous pattern by the sputtering method and so on. This substance is cut into many bar-form pickup stylus materials, and slope 8 is subjected to the mechanical work such as grinding to complete a pickup stylus. At this time, if the mechanical work becomes improper, the substrate is so cut that part 11 having the same width as electrode part 3A is used as electrode part 11, and a new stylus tip part is formed. |
