The present invention provides a large diameter thin-walled fluororesin tube, which has, even with a large diameter (for example, ø 100 mm or more), excellent wall thickness precision and a low degree of stable orientation; and a process for producing the same. Specifically, the present invention relates to a fluororesin tube having an average thickness of 70 μm or less and an outer diameter of 100 mm or more, wherein variation in the tube thickness is within ±20% with respect to the average tube thickness and a degree of orientation (F) is within a range of 0.25 to 0.55.
