description A control device for an internal combustion engine is provided which can stabilize behavior when a fuel injection valve is opened, and reduce a variation in the amount of fuel injection of the fuel injection valve. A control device (200) for an internal combustion engine includes high voltage difference detection means (404) for obtaining a difference between a predetermined reference voltage (403) and a real high voltage detected by a high voltage detection means (402), drive current difference storage means (406) for storing in advance the amount of device difference variation of a real drive current detected by drive current detection means (408), and drive control value correction means (409) for correcting at least one of a target value of a drive current to a fuel injection valve (105) and a target value of a drive time, on the basis of at least one result of the high voltage difference detection means and the drive current difference storage means, and corrects a target control value of the fuel injection valve on the basis of at least one detection result of the variation of the detected high voltage and the variation of the current for driving the fuel injection valve.
