Zusammenfassung:PROBLEM TO BE SOLVED: To provide an internal combustion ignition system which can prevent malfunction by a noise upon ignition of other cylinder engines even when other internal combustion ignition systems are connected to a power source line.SOLUTION: An igniter 60 includes a first input terminal 61 which receives an ignition signal from an ECU 20 as input, a first power source terminal 62 which is electrically connected to the power source line 40 to which a power source voltage is applied, and a control IC 65. Further, the control IC 65 has a second input terminal 65b which receives the ignition signal from the first input terminal 61 as input, and a second power source terminal 65a to which a voltage is applied through the first power source terminal 62, and drives a switching element 66 according to the ignition signal to thereby cause an ignition plug to perform ignition. Further, the control IC 65 incorporates a diode element 67 in which an anode is connected to the second input terminal 65b and a cathode is connected to the second power source terminal 65a.
