PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine which can suppress the deterioration of engine acceleration performance due to excessive increase of an intake air amount at acceleration under a low engine rotation speed condition. SOLUTION: An internal combustion engine 100 includes a working angle varying mechanism 30 capable of varying a working angle of an intake valve 11. An electronic control device 60 of the internal combustion engine 100 sets a control target value of the working angle on the basis of an acceleration request of the engine and executes acceleration control for increasing the working angle to become the control target value. The electronic control device 60 gradually increases the working angle of the intake valve 11 in the acceleration control on the condition that the engine rotation speed is lower than prescribed determination speed and the control target value of the working angle is bigger than a prescribed determination value.
