A control apparatus for an internal combustion engine in the present invention is a control apparatus for an internal combustion engine that includes a fuel injection valve (12) having a nozzle body (12a) that includes a fuel receiving part (12d) provided at a downstream side of a seat part (12a1) with which a seat contact part (12b) of a needle valve (12b) comes into contact, and a plurality of nozzle holes (12e). The control apparatus executes one or a plurality of small injections during one cycle in addition to main injection for generating a torque of the internal combustion engine (10). Further, the control apparatus increases fuel injection amount of a first small injection at the current cycle at the time of low load operation while decreases the fuel injection amount of the first small injection at the time of high load operation, when post injection has not been executed in the last cycle of the internal combustion engine (10) and the small injection is executed first at the current cycle in a case in which a variation in the learned value for fuel injection amount of the learning control is present.
