A curtain airbag device includes an airbag including, on one end side in a vehicle front-rear direction, an inflation portion configured to be inflated by a gas, and a non-inflation region into which the gas does not flow. In a state where the airbag is inflated and deployed, the non-inflation region covers a part of an opening among the plurality of openings, and the inflation portion is disposed to surround the non-inflation region, the opening being located at endmost in a vehicle longitudinal direction. In a case where an impactor strikes the opening located at the endmost, the impactor comes into contact with the non-inflation region, and a lower inflation portion of the inflation portion is sandwiched between a lower end of the impactor and the interior materials of the vehicle side portion, the lower inflation portion being located on a vehicle lower side of the non-inflation region.

The curtain airbag device includes: an inflator; an airbag; and a restricting member. The airbag includes an outer circumferential joining portion forming a bag body, a gas inlet portion, and a joining portion which is arranged in a region surrounded by the outer circumferential joining portion.
