Abstract

A spark plug has a lower capacitive part and an upper inductive part including a mandrel (8) surrounded by a coiling with a closed coiled winding (51). An insulator (7) is interposed between an external envelope (6) and the coiling. A ring (9) made of ferromagnetic material is arranged at an axial end of the coiling and has a radial face lying adjacent to a coil (51b) of the coiling. The ring has radial thickness and radius equal to a radius of the coil. An axial height of the ring is equal to five times the diameter of a wire constituting the coiling.
