An ignition spark plug for an internal combustion engine comprises a body, an insulator, a central electrode and a side electrode which forms a discharge gap with the end face of central electrode. The bent part of the side electrode is performed as a plate with a convex curved surface. On the working surface of the side electrode a micro-forehearth is located, which ends with a slotted nozzle tangentially oriented to the concave curved surface of the plate which fit to the upper part of slotted nozzle. |
