摘要： PROBLEM TO BE SOLVED: To provide an ignition device of an internal combustion engine in which an ignition signal and a fail signal are transmitted on the same signal line and mis-ignition is not caused even if disturbance is applied when the fail signal is transmitted.
SOLUTION: The ignition device of an internal combustion engine includes an electronic control unit which outputs the ignition signal, and an igniter which conducts or cuts off the current of a primary coil by a switching element based on the ignition signal so as to generate high voltage for ignition in a secondary coil, detects the fail signal resulting from the ignition and transmits the same to the electronic control unit. The ignition signal and the fail signal are transmitted on the same line. The igniter has a primary waveform shaping circuit which turns the switching element ON when the voltage of an input to which input resistances are connected in parallel becomes higher than a predetermined reference voltage when the ignition signal is passed, and a pulse output circuit which passes to the input resistances the fail signal of the current value suppressed in such a manner that the potential of the input becomes lower than the reference voltage when the ignition signal is passed to the input resistances.
