A head-protecting airbag device comprising a housing adapted to be mounted on an upper periphery of a window disposed at a side of a front seat of a vehicle and an airbag that is stored in the housing in such a configuration that is folded up through a vertical size reducing folding that brings a lower edge of the airbag as unfolded flatly close to an upper edge of the airbag, the airbag comprising a front inflatable shielding region that is inflatable with an inflation gas fed from an inflator in such a manner as to separate an inboard side wall and an outboard side wall while unfolding downward from the housing for covering an inboard side of the window, the front inflatable shielding region comprising a main inflatable region and a sub inflatable region that is disposed in front of the main inflatable region and is in communication with the main inflatable region and completes inflation after the main inflatable region has completed inflation, the sub inflatable region comprising at a lower end thereof as fully inflated a supportive inflatable region that is deployable at and supported by an inboard side of a vehicle body member of the vehicle which is disposed below a beltline of the window at full inflation of the airbag, wherein: prior to the vertical size reducing folding, the airbag has been subjected to an inward folding that folds a front lower corner of the sub inflatable region as unfolded flatly on a crease extending obliquely rearward and downward from a front edge to the lower edge of the airbag and locates the front lower corner of the sub inflatable region at a position on an inboard side of the inboard side wall deployable above the beltline.
