Abstract
An igniter includes a switching element, a control circuit section, and a protection element. The switching element is connected to a primary winding of an ignition coil. The control circuit section is configured to control operation of the switching element. The protection element is configured to electrically protect the control circuit section. The switching element and the protection element are formed in the same semiconductor chip, and are mounted on the same lead frame.
