ABSTRACT:
An ignition apparatus for an internal combustion engine is able to reduce generation of noise and energy loss due to wiring to a substantial extent. A capacitor 4 is connected at one end thereof to a DC power supply so as to be charged thereby, and at the other end thereof to an ignition coil 5. A switching element 9 is connected between the capacitor and a primary winding of the ignition coil to form part of a discharge path through which the capacitor discharges. The switching element is made conductive by means of an ignition or trigger signal which is generated by a signal generator in synchronism with the rotation of the engine, so that the charged capacitor discharges through the primary winding of the ignition coil. The capacitor, the ignition coil and the switching element are formed integrally with each other, housed in a single casing 13 and connected to each other without the use of a wire harness.
