PROBLEM TO BE SOLVED: To provide a method for producing a tube, which can effectively decrease a void percentage. SOLUTION: The production method includes the process for obtaining an intermediate molding 6 by winding a fiber-reinforced resin member containing fibers and a matrix resin onto a mandrel 2, the process for winding a wrapping tape onto the peripheral surface of the intermediate molding 6, the curing process for curing the matrix resin by heating the intermediate molding 6 with the wrapping tape wound, and the process for obtaining a cured tube by extracting the mandrel 2 and removing the wrapping tape after the curing process. A fabric tape 8 is used as the wrapping tape. The curing process includes the first heating step of heating the intermediate molding at a temperature of 70 to 90°C for 120 to 4,320 min and the second heating step of heating the intermediate molding at a temperature of 120 to 200°C for 10 to 60 min after the first heating step.
