Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an air intake device that can avoid inconvenience due to a temperature rise of combustion air by preventing pressurized air at a raised temperature from being fed to an internal combustion engine.SOLUTION: In a vehicle-mounted air intake device 10, an intercooler 23 cools pressurized air for combustion that is pressure-fed by a supercharger 20 driven by using an exhaust gas within an exhaust pipe 112, and subsequently the pressurized air is sucked by an internal combustion engine 101 via an intake duct 111. The vehicle-mounted air intake device 10 includes: a bypass duct 24 that is communicated with the upstream and downstream sides of the intercooler of the air intake pipe and comprises a bypass path of the pressurized air; an adjusting valve 25 for switching so that the pressurized air passes via the air intake pipe or the bypass pipe; and an ECU 102 that determines whether cooling performance of the intercooler deteriorates, and adjusts and operates the adjusting valve so that the pressurized air passes the bypass pipe in performance deterioration.
