ABSTRACT:
An inspection object constructed of an ignition plug and an ignition coil is inserted in an inspection housing that does not have a ground electrode. A voltage generated in the ignition coil is measured while the inspection object is housed in the inspection housing. Electrical discharge does not occur because the ground electrode is not provided. Therefore, the voltage generated in the ignition coil is properly measured for quality inspection of the ignition coil.
