To provide a method for measuring the electric conductivity of conductive fiber under low applied voltage in order to grasp the electric characteristics of a conductive fiber which causes no trouble of the short-circuit due to reduction in electric conductivity under relatively low voltage, such as inside an electronic appliance and the like.
The applied voltage dependency of the electric conductivity is measured by changing the volume content of the conductive fine particles in the conductive layer of the conductive fiber, and which is shown in graphic curves. Individual curves are overlapped by horizontally moving them to obtain a synthetic curve and an extrapolated electric conductivity under low applied voltage is known from the synthetic curve.
