Abstract

To provide an ignition device advantageous in cost and space by using an inexpensive small-sized Zener diode having a Zener voltage lower than an induced voltage generated at a primary current supply timing, so as to prevent sparking of a spark plug due to the induced voltage. An ignition device for an internal combustion engine, includes a Zener diode provided on the secondary lower-voltage side of an ignition coil. The Zener diode comes into conduction at a voltage lower than an induced voltage generated at a primary current supply timing.
