摘要： A decrease in yield and degradation of productivity can be avoided when a spark plug having an insulator with low mechanical strength is manufactured. In a second process, a terminal electrode 15 is inserted to a predetermined position in a state where an insulator 12 is heated to a temperature equal to or greater than the softening temperatures of first to third powder materials 16P, 17P, and 18P such that the first powder material 16P becomes a first conductive sealing material layer 16, the second powder material 17P becomes a resistor 17, and the third powder material 18P becomes a second conductive sealing material layer 18. In addition, a speed at which the terminal electrode 15 is inserted is reduced between the start and the end of the second process.
