The invention provides a manufacturing method of a cooling pipe unit for cooling a high-temperature load device, which can stably fix an in-pipe straightening tool to an inner peripheral surface of a cooling pipe while maintaining an appearance shape and an outer diameter size of the cooling pipe, the in-pipe straightening tool, the cooling pipe, and a fixing structure of the in-pipe straightening tool.A fixing structure of an in-pipe straightening tool includes: a cooling pipe inside which fluid circulates; and the in-pipe straightening tool which has a belt-like shape twisted into a spiral shape, which is stored inside the cooling pipe in a pipe axial direction of the cooling pipe as a longitudinal direction, and which straightens the fluid circulating inside the cooling pipe. The in-pipe straightening tool 36 includes at least one fixed part for being fixed to the inside of the cooling pipe. The cooling pipe includes at least one fixing part for fixing the fixed part to an inner peripheral surface of the c
