An ignition device includes an igniter fixed to an igniter collar, a first cup member filled with a gas generating component therein, and a second cup member. The first cup member covers the igniter collar to enclose a portion including an ignition portion of the igniter. The second cup member covers the igniter collar to enclose the first cup member. A gap is formed between an outer surface of the first cup member and an inner surface of the second cup member to function as a heat insulating layer. The first cup member has a first opening, and the second cup member has a second opening. At least one of the first opening and the second opening is closed before actuation and is opened only when gas is generated from the gas generating component.
