Abstract: The present invention is provided to suppress the power consumption, the calorific value, and the volume of an ignition device in an internal combustion engine while suppressing failures in igniting fuel by an ignition plug. To achieve this, a control device 1 for the internal combustion engine includes an ignition control unit that controls energization of an ignition coil 300 that gives electric energy to an ignition plug 200 that discharges in a cylinder 150 of an internal combustion engine 100 to ignite fuel. The ignition control unit controls energization of the ignition coil 300 so that first electric energy is released from the ignition coil 300 while second electric energy is released as electric energy superposed on the first electric energy, the second electric energy changing based on a gas state around the ignition plug 200.
