<p>PROBLEM TO BE SOLVED: To achieve both improvement in durability and improvement in noise reduction effect with respect to reduction in the diameter of an ignition plug.SOLUTION: In a conductive adhesive layer 14 provided on the base end side of a noise prevention resistor 13 incorporated in an ignition plug 100, a taper TP is provided which is reduced in diameter toward the tip side, and an inner diameter IDof a resistor housing part is more reduced in diameter than the inner diameter IDof an axial housing part, thereby capable of achieving the improvement in a resistance life by uniformizing the sintering density of a resistor, the stabilization in a resistance value, and the reduction in noise by making electrostatic capacitance on the resistance base end side large.</p> |
