PROBLEM TO BE SOLVED: To provide an electric conductor inspecting apparatus for precisely inspecting the state of an inspection target without any contact when the inspection target is a conductor. SOLUTION: Two sensor plates 570, 580 are arranged nearly in parallel near a conductor 520 to be inspected, where an inspection signal is fed from a power-feeding section. The shape of a conductive tab opposite to the sensor plate 570 is inspected according to a measurement level from the sensor plate 570. Simultaneously, a detection signal from the sensor plates 570, 580 is subtracted by a subtractor 550. A detection value from one sensor plate is subtracted by a subtraction result using a divider 560 for normalizing a detection value from one sensor plate. The relative detection signal value ratio from both the sensor plates is detected for obtaining a detection result corresponding to the distance between the sensor plate and the conductor 520 as X.
