The present invention relates to a method for manufacturing a solid body having a superhydrophobic surface structure formed by using a surface treatment of a metal body, a replication process, and a polymer sticking phenomenon to increase efficiency of fluid transfer and prevent foreign materials from being accumulated in the tube, and a superhydrophobic fluid transfer tube using the method. The superhydrophobic fluid transfer tube includes a fluid guider and a solid body provided on a fluid contact surface of the fluid guider and has micrometer-scaled unevenness and nanometer-scaled protrusions. In the method, a plurality of nanometer-scaled holes are formed on a surface of a metal body through an anodizing process, a replica is formed by immersing the metal body provided with the nanometer-scaled holes in a non-wetting polymer material and solidifying the non-wetting polymer material, the solid body having the superhydrophobic surface is formed by removing the metal body and an anode oxide from the replica, and the solid body is provided to a fluid contact surface of a fluid guider for guiding a fluid.
