An igniting agent includes a powder of a Mg.Al alloy containing Mg: 55 to 70 wt % and Al: the balance. At least one selected from the group consisting of Ca, Mn, Li, Si, Sb, Sr, Zn, Zr, Sc, Y, Sn, Ba, and rare earth metals may be added in an amount of 0.5 to 10 wt %. An initiator is loaded with the igniting agent. A gas generator incorporates the initiator. The igniting agent provides high ignition speed and good grindability.
