The airbag apparatus can be housed in a small space, and is capable of absorbing an impact at a time of a secondary collision in a wide area even though the airbag is compact-sized. The airbag 20 includes a first expanding portion 20A, a folding back area 20f, and a second expanding portion 20B lining in a longitudinal direction, in which the first expanding portion 20A and the second expanding portion 20B are folded back at a folding back line 20g in the folding back area 20f, and are housed in an overlapping state ( Fig. 9 ). |
