PROBLEM TO BE SOLVED: To provide an intake control device for an internal combustion engine controlling the engine to a stable idling operation condition at an early stage by harmonizing intake air flow rate learning value by an intake air flow rate learning means and deposit loss compensation rate. SOLUTION: The intake control device for the internal combustion engine is provided with an intake air flow rate control means regulating detected intake air flow rate to target intake air flow rate, an intake air flow rate feed back control means regulating target intake air flow rate to converge detected idling rotation speed at a time of idling operation to target idling rotation speed, an intake air flow rate learning means learning compensation rate of target intake air flow rate by the intake air flow rate feed back control means as intake air flow rate learning value and renewing target intake air flow rate before learning based on the value when a predetermined learning condition is established. The device is provided with a loss flow rate calculation means calculating loss flow rate of intake air in an intake air passage and a loss flow rate compensation means executing increase compensation of target intake air flow rate and decrease compensation of the intake air flow rate learning value based on loss flow rate.
