An intake passage communicating with a cold air duct and a hot air duct, an air control valve that opens and closes the hot air duct to adjust intake air temperature, and a negative pressure responsive valve switching device that drives the air control valve in a closing direction. , a negative pressure introduction path for introducing suction negative pressure into the valve switching device, a thermosensor that responds to an increase in ambient air humidity, and a thermosensor that is interposed in the negative pressure introduction path and opens in conjunction with the thermosensor. In the intake air control device comprising a valve device that controls the driving of the valve switching device by introducing air into the valve negative pressure introduction path, a wax-type thermosensor that immediately responds to thermal expansion of the thermosensor is used as the thermosensor. At the same time, the drive control of the valve switching device is almost completed in the initial operating range of the wax-type thermosensor, and the valve switching device is further opened in the latter operating range of the thermosensor, thereby opening the negative pressure introduction path. An intake control device for an internal combustion engine, characterized in that the amount of air flowing into the intake passage is compensated for through the intake passage.
