A control device for an internal combustion engine which can highly precisely realize required torque including a high-frequency component with high responsiveness. The control device sets torque with a low frequency included in the required torque as an air quantity controlling torque, and calculates a target air quantity for realizing the air quantity controlling torque based on data in which a relationship of the air quantity and torque is set. The control device controls the air quantity in accordance with the target air quantity. Further, the control device sets torque including both a low frequency and a high frequency as air-fuel ratio controlling torque, and calculates an air-fuel ratio corresponding to the air-fuel ratio controlling torque and a present air quantity as a target air-fuel ratio. The control device controls a fuel injection amount in accordance with the target air-fuel ratio.
