PROBLEM TO BE SOLVED: To provide a fluid compressor capable of securely flowing water sucked into a pump chamber and water produced in the pump chamber by dew formation to the outside through a discharge port formed at the bottom of the pump chamber without leaving at the bottom of the pump chamber. SOLUTION: The discharge port 40 for discharging hydrogen offgas compressed based on the rotating motion of rotors 33 and 34 to the outside of the pump chamber 17 is formed at the bottom 39 center of the pump chamber 17, and a guide face 41 having a downhill grade toward the opening edge 40a of the discharge port 4 is formed near the discharge port 40. The guide face 41 is formed in a roughly funnel surface shape having a center at the discharge port 40, and functions to lead water accumulated at the bottom 39 of the pump chamber 17 toward the discharge port 40. Accordingly, even if the hydrogen offgas dews in the pump chamber 17 and water is produced, such water is led to the discharge port 40 by the guide face 41 and securely discharged from the discharge port 40, and accordingly, does not remain in the pump chamber 17.
