A head-protecting airbag apparatus comprising:

• an airbag body expanding in a curtain shape disposed in a folded state along a roof side rail across at least a center pillar, the air bag body comprising:
• a gas introducing path formed generally linearly along the roof side rail on only a region corresponding to the roof side rail, one end of the gas introducing path communicating with an inflator, and
• a plurality of inflating chambers formed in only a region positioned below the roof side rail, each one end of the inflating chambers communicating with the gas introducing path,
• wherein the gas introducing path is folded once along a longitudinal direction of the gas introducing path so as to form a vehicle occupant compartment outer side portion thereof and a vehicle occupant compartment inner side portion thereof, the vehicle occupant compartment outer side portion being located outside with respect to the vehicle occupant compartment inner side portion in a widthwise direction of the vehicle, and one end of the vehicle occupant compartment outer side portion communicating with the inflator, and
• the gas introducing path expands before a portion of the airbag body such that the portion of the airbag body except for the gas introducing path expands after being pressed and moved toward a vehicle occupant compartment inner side by the expanding gas introducing path.
