Provided is an ignition control device (30) that can efficiently control the thermal ignition timing for a fuel-air mixture in a combustion region (10). A peak estimation unit (32), an ignition timing determination unit (33), a control timing determination unit (34) and a plasma control unit (35) control the thermal ignition timing for the fuel-air mixture in the combustion region (10) by controlling a pulse generator (36), an electromagnetic-wave generator (37), a mixer circuit (38) and a spark plug (15) so that the amount of hydroxyl radicals in the combustion region (10) is increased during a low-temperature oxidation preparation period that occurs before the heat generation peak that occurs before the thermal ignition of the fuel-air mixture. |
