Igniter assembly and gas generation device

An igniter assembly comprising:

• an ignition device including,
• an igniter including an ignition portion airtightly accommodating an ignition charge, and a conductive portion that supplies an ignition current for igniting the ignition charge,
• an igniter holding portion having a tubular shape and holding the igniter in a state of surrounding the igniter, and
• a fixing member made of a resin, interposed between the igniter and the igniter holding portion, and fixing the igniter to the igniter holding portion;
• a case having a bottomed tubular shape and accommodating a first gas generating agent and the ignition portion of the igniter, on one side in an axial direction of the igniter holding portion;
• and
• a partition wall partitioning an inside of the case into a space in which the igniter and the fixing member are disposed and a space in which the first gas generating agent is accommodated, the partition wall having moisture impermeability, wherein
• the partition wall is fixed in a state of being in contact with the case, and is welded around a perimeter to at least one of the igniter holding portion and the case, and
• wherein the first gas generating agent is disposed on a first side of the partition wall and the ignition charge is disposed on the second side of the partition wall so as the partition wall to directly face the ignition portion.
