A hood airbag device for use in a vehicle, comprising: a gas generating unit that discharges a gas when the vehicle makes a head-on collision with an impact object, the gas generating unit being arranged below a rear end portion of an outer hood panel that serves as an outer plate of a hood; and a left and right airbag, each of which is stored in a folded state below a respective left and right bag-expansion opening formed at the rear end portion of the outer hood panel, in a hood width direction, wherein each airbag is deployed through the respective bag-expansion opening by the gas supplied from the gas generating unit to cover at least the rear end portion of the outer hood panel and a cowl, and each airbag is sized in a vehicle width direction such that, when the airbags are in a deployed state, hood-center side end surfaces of the airbags in the vehicle width direction directly press against each other, and hood-center side end portions of the airbags in the vehicle width direction are bulged to have a thickness greater than that of other portions of the airbags.
