PROBLEM TO BE SOLVED: To provide an ignition control device of a cylinder injection type internal combustion engine capable of restraining electric power consumption by ignition, while preventing a misfire, in the internal combustion engine having an ignition chance of two times of a spray guide system and a wall guide system. SOLUTION: An ion current is detected by an ion current detecting circuit 60 via a spark plug 14, and a misfire determining part 46 in an ECU 40 determines whether or not the misfire is caused in the ignition in the spray guide system on the basis of the ion current. When determining as the misfire, ignition in the wall guide system is also performed. When determining that the misfire is not caused, ignition in the wall guide system is not performed.
