An ignition plug for an internal combustion engine is provided, which includes a pre-combustion chamber cell (150) and at least three exhaust nozzles (160, 170). The pre-combustion chamber cell (150) is disposed to surround a pair of electrodes (140b) in the lower portion of a main cell (110) and is formed in the inner portion where the electrodes (140) are contained. Meanwhile, a circular main exhaust nozzle (160) through which a fluid goes in and out is disposed in the central region of the pre-combustion chamber cell (150). The ignition plug enables the whole engine to have a quick combustion speed. As a result, a more reliable improvement of a combustion performance can be obtained. Also, a fuel-to-air ratio can be enhanced, and an exhaust gas reduction effect can be obtained.
