Abstract

PURPOSE: To achieve the higher reliability of pinhole detection in case-package state by disposing the package to be inspected between a pair of electrodes and applying voltage.
CONSTITUTION: A hermitically closed package 1 such as ampoule which is sealed with conductive liquid in electrical insulation type material is disposed between a pair of opposing electrodes 2, 3 and the specified voltage of the frequency 1kHz or less is applied between the electrodes from a power source 4. When no pinholes and cracks exist in the surface of the package 1, the corona discharging at the normal time is accomplished. On the other hand, when a pinhole or the like exist, a flash over occurs between the electrodes and the sealed content through that pinhole and by detecting the change in the high-frequency component occurring at that time, the pinhole may be detected.
