Abstract
An igniter assembly includes an igniter including a container and an ignition charge. The igniter emits a combustion product of the ignition charge when a lid wall portion is ruptured upon operation of the igniter. The container includes a peripheral wall portion and the lid wall portion closing one end of the peripheral wall portion. The ignition charge is filled in an accommodating space defined by the peripheral and lid wall portions. A tubular wall portion surrounds the peripheral wall portion. The tubular wall portion defines an emitting space in which the combustion product is emitted. The lid wall portion includes an annular outer peripheral region portion connected to one end of the peripheral wall portion and a central region portion positioned inside the outer peripheral region portion in a radial direction. The outer peripheral region portion is formed thicker than the central region portion.
