摘要：
A spark plug (10), for example for an internal combustion engine, having at least one center electrode (11) (high-voltage electrode) and at least one earth electrode (12), and an insulating spark plug insulator (13) and a creepage spark gap (14) between the center electrode (11) and the earth electrode (12). The creepage spark gap (14) has a pattern of islands comprising electrically-conductive material (16) which are insulated with respect to one another and are located on the outer surface zone of the spark plug insulator (13) or on the surface zone of an insulating material wafer (17) attached to outer surface of the insulator (13) of the spark plug (10).
