Abstract

A stylus includes electrically conductive pen body including accommodation chamber and connection portion at end of accommodation chamber, core member mounted in accommodation chamber, and pen cap made of electrically non-conductive material and including conical base, mounting portion located at rear side of conical base and fastenable to connection portion, insertion hole for passing of core member, grooves located at periphery of conical base and conducting layer coated on surface of conical base, surface of each groove and surface of mounting portion for conduction with electrically conductive pen body. After long uses, part of conducting layer in each groove can be maintained intact and in integrity with part of conducting layer at mounting portion. Conducting layer can be positively and electrically conducted with electrically conductive material of pen body to provide effective shielding effect for protection of internal electronic components of stylus against external EMI and static electricity.
