A remaining lifetime estimating method includes a conversion step of converting a total elapsed time of an airbag into a total elapsed time Tb of the airbag at a predetermined temperature t, according to a formula based on the Arrhenius equation; a remaining use time calculation step of calculating a remaining use time Tx of the airbag by subtracting the total elapsed time Tb from a lifetime Ta of the airbag at the predetermined temperature t; a correction step of performing a correction to increase the remaining use time Tx on the basis of a predetermined value Tc proportional to a power supply time to a vehicle; a determination step of determining whether or not the remaining use time Tx corrected is equal to or less than a predetermined value; and a notification step of issuing a notification regarding the lifetime of the airbag.
