    • An ion current detecting device includes an ion current detecting unit which detects ion current based on combustion ion generated after an ignition which is performed in a combustion chamber and an amplifier unit which amplifies ion current detected by the ion current detecting unit. The amplifier unit has an amplification rate which is set so that an output amplified ion current varies nonlinearly with ion current of the ion current detecting unit. Thus, the amplifier unit enables the amplification rate to vary according to a level of ion current. Therefore, ion current can be detected correctly even if a minute ion current is generated when the spark plug malfunctions etc., and even if ion current becomes higher.
