ABSTRACT:
An ignition plug for internal combustion engines in which a spark gap is established between a central electrode and a ground electrode opposed thereto and a spark discharge is generated in the spark gap so as to ignite a mixture, wherein the ground electrode takes a unique form such that it is provided with a kerf, groove, depression, projection or the like at its spark discharge area confronting the central electrode whereby the ignition ability is improved with the result that a lean mixture is useful to reduce the quantity of harmful components in the exhaust gas.
