  "textContent": "A connection portion connecting a center electrode and a terminal metal fixture together in a through hole of the insulator includes a resistor and a magnetic substance structure including a magnetic substance and a conductor and being disposed on a leading end side or a rear end side of the resistor while being positioned away from the resistor. Among the resistor and the magnetic substance structure, a member disposed on a leading end side is defined as a first member and a member disposed on a rear end side is defined as a second member. The connection portion further includes a first conductive sealing portion, a second conductive sealing portion and a third conductive sealing portion. The first conductive sealing portion is disposed on a leading end side of the first member and is in contact with the first member. The second conductive sealing portion is disposed between the first member and the second member and is in contact with the first member and the second member. The third conductive sealing portion is disposed on a rear end side of the second member and is in contact with the second member. Here, the resistor and the sealing portion may be omitted, and connection portion may include the magnetic substance structure including the magnetic substance and the conductor.",
