PROBLEM TO BE SOLVED: To provide a capacitance instruction device.SOLUTION: A capacitance instruction device of the invention comprises: a core part; a holder of the core part; an elastic member; a control plate; a pressure sensitive member; an upper layer shield; a lower layer shield; a tip end cover; and a battery. The core part includes a conductor, and the holder of the core part penetrates the core part. One end of the holder of the core part is wound around the elastic member, and the holder of the core part and the elastic member are electrically connected to the control plate. The pressure sensitive member is positioned on one end of the control plate, the elastic member is compressed by the core part and the holder of the core part, and is brought into contact with the pressure sensitive member for detecting writing pressure of the core part. The upper layer shield and the lower layer shield coat and connect the core part, the holder of the core part, and the elastic member. The tip end cover covers the core part, the upper layer shield, and one end of the lower layer shield and is electrically connected to the control plate. Finally, the battery makes the capacitance instruction device supply electrical energy. |
