    • PURPOSE:To automate the inspection by a process wherein a condom to be inspected which is filled up with a first electroconductive liquid is dipped in a second electroconductive liquid to a position just below the opening thereof, and a process wherein a voltage is impressed between these electroconductive liquids. CONSTITUTION:When a manufactured condom 2 is removed from a manufacturing die 1, it is dipped, together with the die 1, in an electro-conductive liquid 3 to a position near the opening thereof, and supported by a net vessel or a vessel 5 having a porous wall surface in such a manner that the outside of the condom 2 is surrounded by the vessel, and an electroconductive liquid, e.g. water 4, is injected between the condom 2 and the manufacturing die 1. When the die 1 is drawn up while the water is injected, the condom 2 is laid closely on the inside wall 5, and a voltage is impressed in this state. Then a current flows when the condom has a pinhole. This method enables the inspection utilizing a process of removing a finished condom from a manufacturing die, and thus the inspection is automated.
