摘要：
To provide an ignition device advantageous in cost and space by using an inexpensive small-sized Zener diode (23) 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 (19) due to the induced voltage. An ignition device for an internal combustion engine, including a Zener diode (23) provided on the secondary lower-voltage side of an ignition coil (18). The Zener diode (23) comes into conduction at a voltage lower than an induced voltage generated at a primary current supply timing.
