Abstract
This igniter has a heating element, an ignition agent positioned so as to be in contact with the heating element, and conductive pins that pass through an insulating layer, and are electrically connected to the heating element. One end of each conductive pin is exposed through the insulating layer in such a manner that a current supply component, which supplies an ignition current, is connected to the heating element. An IC tag is positioned inside the insulating layer, in the vicinity of the conductive pins.
