PURPOSE: A capacitive touch pen using a pencil lead is provided to reduce manufacturing costs by generating an electric charge by an inducing current as a conductive rubber tip, a metal coupling, a conductive rubber tube, and a pencil lead. CONSTITUTION: A capacitive touch pen(2) combines an upper side of a metal coupling(21) with a lower side of a conductive rubber tip(20). The capacitive touch pen combines an upper side of a conductive rubber tube(22) having an air hole and includes an air cushion chamber. A protection cap(10) is inserted in a pencil and protects a pencil lead(1a). The induced electromotive force combines an upper side of the protection cap with the conductive rubber tube. |
