A gas generator comprises a cylindrical partition wall section (22) provided with gas passage holes (23a, 23b) through which gas generated by the combustion of a gas generation agent passes. Two band-shaped seal tapes (24A, 24B) are continuously adhered to the partition wall section (22) so that: the direction of extension of each of the seal tapes (24A, 24B) coincides with the circumferential direction of the partition wall section (22); and a pair of ends of each of the seal tapes (24A, 24B), the pair of ends being located in the direction of extension of the seal tape, overlaps the adjacent seal tape. The gas passage holes (23b) are closed by overlapping adhesion regions (R1, R2), which are the portions where the adjacent seal tapes (24A, 24B) overlap each other, and the gas passage holes (23a) are closed by non-overlapping adhesion regions, which are the portions where the adjacent seal tapes (24A, 24B) do not overlap each other. |
