PROBLEM TO BE SOLVED: To provide a medical tubular body capable of uniformly polishing on an outer surface and an inner surface with less uneven polishing by using a simple method and an apparatus in a short time and efficiently without damaging the tubular member. A manufacturing method and a manufacturing apparatus are provided. A step of arranging a core material 41 having an outer surface having an uneven surface having an arithmetic average roughness Ra of 1 μm or more and 100 μm or less based on JIS B0601 in a cavity of a tubular member 11, and a liquid and an abrasive material 23 are provided. It has a step of bringing the fluid 22 or the fluid 22 including the gas and the abrasive 23 into contact with the outer surface 14 of the tubular member 11, and by contacting the fluid 22 with the outer surface 14 of the tubular member 11. A method for manufacturing a medical tubular body 1 in which the outer surface 14 of the tubular member 11 is polished, and the inner surface 15 of the tubular member 11 and the core material 41 are in contact with each other to polish the inner surface 15 of the tubular member 11.
