Spark plug for an internal combustion engine

A spark plug for an internal combustion engine, in particular a gas engine, comprising a central electrode and at least one ground electrode group respectively including one or more ground electrode platelets, wherein the central electrode has at least one central electrode platelet having a central electrode surface, wherein the central electrode surface is inclined in a range of between 0° and 50°—preferably at a maximum 45°—relative to a cross-sectional plane transversely relative to the longitudinal axis of the spark plug, wherein each ground electrode platelet of a ground electrode group has a ground electrode surface that faces towards the central electrode surface and that is spaced from the central electrode surface and extends substantially parallel to the central electrode surface, wherein a projection of all ground electrode surfaces of the ground electrode platelets of a ground electrode group on to the central electrode surface associated with them in the direction of a normal vector of the central electrode surface gives in total a notional electrode surface wherein the notional electrode surface is of a size of between 8 mm2 and 25 mm2, characterised in that wherein each ground electrode surface of the ground electrode platelets of a ground electrode group is arranged spaced in a range of between 0.2 mm and 0.8 mm from the at least one central electrode surface.
