PROBLEM TO BE SOLVED: To increase the suction air quantity even at low load, keep an air suction port from becoming negative pressure even at high load, improve follow-up property with respect to the output change of an internal combustion engine, and obtain output of the internal combustion engine installed on highlands as much as that installed on flatlands. SOLUTION: With a supercharge 1, intake air is compressed by rotating a compressor wheel 11 provided coaxially with a turbine wheel 5, which is rotated by having exhaust gas from an engine guided to it, and supplied to an engine combustion chamber. An intake air forced feeding device 35 is provided on the air intake port 15 side of a compressor. The intake air force feeding device 35 includes an air filter 33, an air blowing means 21 for force feeding intake air, and a duct 31. Air intake quantity into the supercharger 1 compressor 11 is increased because all loads from the low load to the high load are pressurized more than before in the vicinity of an inlet 15.
