The present invention relates to a glow plug assembly having a double terminal, which is formed to enable reliable control with a fast response by preventing noise generation caused by grounding, and to this end, the glow plug assembly comprises: a housing extending in the axial direction; a heating tube coupled to the lower part of the housing and filled with insulation powder therein; a cap fixed to the upper end of the housing; a first terminal and a second terminal of which the upper part is fixed to the cap and the lower part enters the inside of the heating tube; and a heating coil of which both ends are coupled to the other ends of each terminal and a winding part is closely arranged on the inner circumferential surface of the heating tube, wherein the other end of the first terminal is coupled to one end of the heating coil such that the first terminal is formed to have a relatively shorter length than that of the second terminal, and the second terminal is formed by downwardly extending in a relatively longer manner than that of the first terminal and has a structure in which the second terminal is induced toward the center of the wound heating coil through a curved part so as to secure an insulation space with the heating coil and is coupled to the other end of the heating coil extending up to the lower part of the inside of the heating tube. |
