摘要： The invention relates to a spark plug (100) for an internal combustion engine, in particular having a high frequency ignition system, having a central electrode (28; 128), a ground electrode (12; 112) and an electrical insulator (18; 118) arranged between the central electrode (28; 128) and the ground electrode (12; 112), wherein a central electrode connecting point (26; 126) for electrically connecting the central electrode (28; 128) to an ignition system is provided on the insulator (18; 118), wherein the central electrode (28; 128) and the ground electrode (12; 112) project beyond the insulator (18; 118) at an axial end (114) of the spark plug (100) and each form, with a part projecting axially beyond the insulator (18; 118), a central electrode end (140) and a ground electrode end (142), wherein the central electrode end (140) and the ground electrode end (142) are arranged and embodied in such a way that an axial region (170) of a gap (146) is formed between them in an axial direction, wherein the axial region (170) of the gap (146) is spaced apart from the insulator (18; 118), wherein at least one additional electrode (150) is provided which projects beyond the insulator (118) at the axial end (114) of the spark plug (100) and forms, with a part which projects axially beyond the insulator (118), an additional electrode end (154). In this case the additional electrode (150) is arranged electrically insulated from the ground electrode (112) and the central electrode (128), on the spark plug (100), wherein the additional electrode end (154) projects into the axial region (170) of the gap (146) between the central electrode end (140) and the ground electrode end (142) or is arranged into a region (170) of the gap (146) which is radially adjacent to the axial region (170) of the gap (146), and as a result divides the gap (146) into two ignition spark end gaps (156, 166).
