Abstract

PURPOSE: To improve the noise preventive performance of an ignition plug by inserting tightly a filler of insulating material into a hollow hole of an insulator tube to form glassy resistor of small sectional area filling the gap among the fillers.
CONSTITUTION: A ceramic cylinder 7 is interposed between a central electrode 5 and a terminal electrode 6 in the hollow hole of an insualtor tube 3 to fill a hole 8 or hole group 9 formed at the cylinder 7 to thus form fine and long glassy resistor 1' therewith. This resistor 1' is reduced in cross sectional area thereof and lengthened in length to thereby eliminate necessity of glassy resistance material of high specific resistance to thereby utilize the resistor 1 itself as a glass seal 2.
