Zusammenfassung:	Disclosed is an austenitic stainless steel pipe having excellent wrinkle resistance. The austenitic stainless steel pipe includes, based on % by weight, silicon (Si): 0.1 to 0.65 %, manganese (Mn): 0.2 to 3.0 %. nickel (Ni): 6.5 to 12.0 %, chromium (Cr): 14.5 to 20.5 %, copper (Cu): 6.0 % or less (excluding 0), the sum of carbon (C) and nitrogen (N): 0.13 % or less (excluding 0), and the remainder being Fe and unavoidable impurities, wherein the austenitic stainless steel pipe satisfies Equation (1) below concerning an outer diameter (D) and a thickness (t) thereof and has a yield strength of 195 MPa or less: D/t2:20 ... Equation (1). (Fig. 2)
