PURPOSE:To obtain a low-cost hollow stylus having no possibility of clogging caused by the inclusion of the scum of a blank cap and having a thin outer dimension by providing a closed slant cut tip end, a flat part continuously formed from the slant cut tip end, and at least one through hole formed on an edge part of the flat part. CONSTITUTION:A slant cut tip end part 14 is formed on the tip end of a hollow stylus 13, and the tip end of a hollow hole 13a is completely closed. A flat part 15 is formed continuously to the slant cut tip end part 14. A crosswise hole (through hole) 16 is formed on the edge 15a of the flat part 15 so as to penetrate into the hollow hole 13a of the hollow stylus 13. By using this method for forming the crosswise hole 16 on the edge 15a of the flat part 15, a through hole can be formed in a remarkably simple manner even on the thin hollow stylus 13. In addition, the slant cut tip end part 14 and the flat part 15 are simultaneously formed by press working without the need for any complex machining. |
