PURPOSE:To eliminate the need for shorting every other electrodes with a common electrode for the purpose of inspection by detecting the short circuit in band-shaped electrodes by using a driving head for generating induced current and detecting head for detecting the induced current. CONSTITUTION:The driving head 5 and the detecting head 6 are disposed on an electrode plate 1 to generate the induced current in one band-shaped electrode 12A positioned in the middle of an aperture 51 and to detect the induced current from the other band-shaped electrode 12B positioned in the middle of an aperture 61. The induced current generated in the electrode 12A, therefore, flows to the electrode 12B through the shorted point if there is an inter-electrode short circuit between the electrode 12A and the electrode 12B. The induced current detected by the electrode 12A is amplified and is inputted to a measuring instrument. The need for shorting every other band-shaped electrodes at one end with the common electrode for the purpose of inspection is thereby eliminated. |
