ABSTRACT There is provided a driver's seat airbag configured to be mounted on a steering wheel of a vehicle. A bottom wall portion of the driver's seat airbag is configured to be supported on a ring portion of the steering wheel when receiving a driver after completion of inflation of the driver's seat airbag. Upon completion of the inflation, an outer peripheral wall of the driver's seat airbag has a substantially regular polygonal pyramid shape which includes: the bottom wall portion having a regular polygonal shape, the bottom wall portion provided with an inlet port for introducing inflation gas therethrough, a peripheral edge of the inlet port configured as a mounting seat and vicinities of corner portions of an outer peripheral edge of the bottom wall portion configured to be supported on the ring portion; and a peripheral wall portion formed by mutually joining substantially triangular panel-like side wall portions extending from locations of each side of the regular polygonal shape in the outer peripheral edge of the bottom wall portion toward an apex at a side of the driver. Each of the side wall portions has the same shape, respectively and lengths of mutually joined areas of the side wall portions from each of the corner portions of the bottom wall portion to the apex are equal.
