Abstract
A plurality of cores of a multi-core cable are collectively conducted at first ends side thereof and are isolated from one another at second ends side thereof. The cores are engaged at the first ends side with grooves formed on a movable member one by one so as to be picked up and are sequentially transported toward an electrode. The picked-up core is cut during :its transportation so as to be electrically separated from a collective conducting part at the first end side. A high voltage is charged to the picked-up core through the electrode and based on an electric conduction characteristic of its charging current a judgment is made about whether there is a defective contact (dielectric breakdown) between the picked-up core and other cores. Further, the electric charge of the picked-up core is discharged, the picked-up core is recharged, and based on electric conduction characteristics of these discharging current and charging current a confirmation that the above judgment was not a misjudgment is made. After the discharging, the movable member is moved again and then the next picked-up core is tested.
