In a control apparatus for an internal combustion engine, an amount of electricity to be generated by an alternator (a target charging voltage) is set based on a vapor concentration of vaporized fuel when a purge execution condition is met for purging the vaporized fuel collected by a canister, whereby a fluctuation in rotation in an idling operation state is suppressed, an appropriate purging treatment of the vaporized fuel is allowed, and the drivability is improved.
