PROBLEM TO BE SOLVED: To provide a method for manufacturing capable of easily obtaining a tubular body which is minute in diameter and even. SOLUTION: The tubular body (Q) is obtained by the method for manufacturing the tubular body comprising: flowing a molten matter (A0) of a material substance (A) or a liquid precursor (a) and a liquid (B) or a gas (C) as two laminar flows so as to form an annular part of the molten matter (A0) or the liquid precursor in a micro-reactor by introducing the molten matter (A0) of the material substance (A) or the liquid precursor (a) constituting the tubular body into an outer tube (P2) in the laminar state and introducing the liquid (B) or the gas (C) which is insoluble with the molten matter (A0) or the liquid precursor into an inner tube (P1) in the laminar state using the tubular micro-reactor (R) having an inner diameter of 0.002-2 mm including an introducing part of two folded coaxial tubes comprising the inner tube (P1) having an inner diameter of 0.001-1 mm and the outer tube (P2) having an outer diameter of 0.002-2 mm; and hardening or polymerizing the molten matter (A0) or the liquid precursor (a).
