To obtain a polyimide tubular product free from blister and thickness deviation with surface smoothness and high roundness, free from air foams in the coating film and high in light transmittance, and to provide a method for producing the transparent polyimide tubular product at low cost in high productivity.

The transparent polyimide tubular product is obtained by imidation of a polyimide precursor solution that is prepared by reaction in a polar solvent between at least one diamine selected from those of chemical formula(A) and (B) or its derivative and at least one tetracarboxylic dianhydride or its derivative. For this transparent polyimide tubular product, the water vapor permeability of the coating film thereof is 10-50 g/m2×24 h.
