In the auxiliary air amount control device, an auxiliary air amount control device for determining a deceleration operation state in which the actual amount of auxiliary air is insufficient than the amount of auxiliary air required by the engine deceleration operation conditions even if the auxiliary air amount control valve is controlled to the maximum opening degree. an air amount insufficient state determination means; and a deceleration idle up control valve that forcibly controls the idle up control valve to open when the auxiliary air amount insufficient state determination means determines a deceleration operation state in which the amount of auxiliary air is insufficient. An auxiliary air amount control device for an internal combustion engine, comprising: opening control means.
