An internal combustion engine according to the present disclosure has an ignition coil and an injector that share a power source, and has a controller that controls energization to the ignition coil and energization to the injector. The controller executes setting processing and correction processing. In the setting processing, the controller sets an energization period of the ignition coil in accordance with an operating condition of the internal combustion engine. In the correction processing, when the energization period of the ignition coil overlaps with an energization period of the injector, the controller corrects the energization period of the ignition coil so as to reduce an overlap period between the energization period of the ignition coil and the energization period of the injector.
