Terminal is located at a rear end side with respect to thread portion of metal shell. Detector electrode is provided at a portion located at a top end side with respect to a top end of contact portion between reduced diameter portion and shelf portion or packing in a space formed between outer periphery of insulator and inner periphery of the metal shell. The detector electrode and the terminal are connected by conductor. The detector electrode and the conductor are insulated from center electrode, the metal shell and ground electrode. Since the detector electrode is located in the space between the outer periphery of the insulator and the inner periphery of the metal shell, an early detection of the flame kernel occurring in this space can be possible.
