Abstract (en)

[origin: DE10011705A1] The sparking plug has a center electrode and a truncated cone shaped basic body with an end facing toward the combustion chamber, and includes a fixed noble metal disc. The noble metal disc (8) has a truncated cone shape. The diameter of the endface region (51) of the basic body , facing the combustion chamber, corresponds to the diameter of the endface of the noble metal disc facing the combustion chamber. Independent claims are included for a manufacturing method for the electrode of the spark plug.
