An internal liquid pathway in this liquid supply type screw compressor includes a slit-like injection section open to a bore and injecting liquid into an operating chamber. A casing is provided with a first casing and a second casing which are separated along a plane intersecting the axes of screw rotors at an axial position between the suction-side end surfaces and the discharge-side end surfaces of the rotor tooth sections of the screw rotors.
