Disclosed is a curtain bag that can obtain a necessary inflated state in a short period of time without applying excessive localized force to a peripheral joining section or an inner joining section, and that is improved in the ability to suppress the ejection of passengers out from a vehicle specifically by a lateral collision. A portion of the curtain bag and/or the peripheral edge is shaped so as to snag the bottom sill of a window, and the inner joining section of the region that contacts the section below the bottom sill of the window is shaped with a plurality of dots and/or given an expandable form across effectively the entire surface and/or given a form that has increased bending stiffness.
