Abstract
The invention relates to a spark plug for an internal combustion engine, in particular a gas engine. The spark plug includes a middle electrode and at least one earth electrode group, each comprising one or more earth electrode platelets. The middle electrode includes at least one middle electrode platelet having a middle electrode surface, and the middle electrode surface is inclined in a range from 0° to 50°, preferably to at most 45°, to a cross-sectional plane transverse to the longitudinal axis of the spark plug. Each earth electrode platelet of an earth electrode group has an earth electrode surface facing towards the middle electrode surface, spaced apart from the earth electrode surface and running substantially parallel to the earth electrode surface.
