PROBLEM TO BE SOLVED: To provide a method of manufacturing a tube body and a tube body capable of fixing a resin mesh tube to an exterior member. SOLUTION: The method of manufacturing a tube body is such that a resin net-like tube 11 having a first outer diameter and a first inner diameter is stretched by pulling both ends in a longitudinal direction to make the first outer diameter and the first inner diameter. Of the resin-made exterior member 12 having an inner diameter close to that of the first outer diameter of the mesh tube 11 in a tensioned state so that the integral body 20 of the mesh tube 11 and the exterior member 12 is formed. A cored bar having an outer diameter similar to that of the first inner diameter is inserted into the inner hole of the reticulated tube 11 of the integrated body 20, and ultrasonic horns are pressed against the entire circumference of both ends of the integrated body 20 to apply the metal. By shaking, the exterior member 12 is melted, the welded portion 11a in which the exterior member 12 is embedded in the mesh tube 11 is formed on the entire circumference of both ends of the integrated body 20, and the welded portion 11a is cooled.
