PURPOSE:To reduce the cost of work for forming a starting material into a specific shape by obtaining a scan-out surface having desired electrode width in the process of forming a projecting part under a stylus base. CONSTITUTION:The projecting part 20 projects further downward from the reverse surface 41 of the stylus base 40 and has a bottom surface 21 slidably in contact with a video disk and the 1st and the 2nd flanks 24 and 25 which extend respectively while the 1st immaginary surface 50 running through the bottom surface 21 and crossing the scanning stylus longitudinally is interposed and also have lower edges 22 and 23 formed by the bottom surface 21. Further, this projection 201 has the 3rd and the 4th flanks 28 and 29 which extend respectively while the 2nd immaginary surface 52 crossing the 1st immaginary surface 50 and crossing the scanning stylus longitudinally through the bottom surface 21 is interposed and are formed by lower edges 26 and 27 and bottom surface 21, and the 5th flank 31 having a ridge edge 30 which is placed between the 1st and the 3rd flanks 24 and 28, forms the bottom surface 21 and is specified in length within the width of a signal track. |
