Abstract
A line sensor includes a sensor cord including a resilient hollow insulator and two electrical wires arranged along an inner circumferential surface of the hollow insulator in an electrically non-contact state with each other, a constant current source which is connected to one of the two electrode wires at one end of the sensor cord, and a detecting device for detecting a pressed position. The other electric wire is grounded at the other end of the sensor cord. The two electric wires include a resistance wire having a resistance of 1 kΩ/m or more. The detecting device detects a voltage of the resistance wire at one end of the sensor cord to detect the pressed position in a longitudinal direction of the sensor cord based on the detected voltage.
