ABSTRACT:
A self-heating type ignition plug according to the present invention includes a base portion having a fixing portion formed on an outer wall thereof and a terminal insulately provided therein and connected to an electrical source; an ignition means, integrally connected to the base portion, having an ignition surface formed on a wall surface thereof and composed of a catalyst comprising a transition material, thereby to come in contact with the fuel; and a heating means having a resistive exothermic element connected to the terminal of the base portion, the resistive exothermic element being provided adjacent to the ignition surface within the ignition means, whereby the fuel may be ignited and burned as a whole by the ignition surface of the catalyst which is maintained to a preset temperature due to the oxidation reaction of the catalyst and the fuel being in contact therewith after the heating means is deenergized.
