Abstract: <P>PROBLEM TO BE SOLVED: To provide a screw compressor having tooth thickness of a female rotor on a discharge port side thicker than that on a suction port side.  <P>SOLUTION: In this screw compressor, air sucked from a suction port 5 is discharged from a discharge port 7 by the female rotor 3 and a male rotor 4 having mutually engaged teeth 3b and teeth 4b.
