A screw rotor is for use in a screw pump (11) that pumps fluid by rotation of a pair of screw rotors (13,14) engaged with each other in a rotor housing (12). The screw rotor includes a multiple-thread portion (26,34) for pump suction side and a single-thread portion (21,37) for pump discharge side. The screw rotor is formed so that the tooth profile (G21,G22) of the multiple-thread portion is connected to the tooth profile (G21,G22) of the single-thread portion through a boundary plane that is perpendicular to the rotation axis (151,161) of the screw rotor. The first curved portion (A1C1,A2C2) coincides with the third curved portion (46A,46B) in the boundary plane.
