Beschreibung
Zusammenfassung:	An igniter of the present invention has an insulated gate semiconductor device having a collector terminal, an emitter terminal and a gate terminal, a current control circuit which limits current by controlling voltage at the gate terminal when current for flowing through the insulated gate semiconductor device exceeds a fixed value, a voltage monitor circuit for detecting a potential of the collector, and a control current adjusting circuit for controlling current which flows through the gate terminal by receiving output from the voltage monitor circuit.
