Provided is an austenitic stainless steel sheet which has a product of the 10% flow stress at a strain rate of 1000/s and the uniform elongation at a strain rate of 0.1/s of 450 MPa or more and also has high strength at a high strain rate and improved ductility at a low strain rate. An austenitic stainless steel sheet containing, in % by mass, 0.02 to 0.30% of C, 10.0 to 25.0% of Cr, 3.5 to 10.0% of Ni, 0 to 3.0% of Si, 0.5% to 5.0% of Mn, 0.10 to 0.40% of N, 0 to 3.0% of Mo, 0 to 3.0% of Cu, 0 to 0.10% of Ti, 0 to 0.50% of Nb and 0 to 1.0% of V, wherein the value determined by the following formula: C + 3 * N is 0.4% or more, and the remainder is made up by Fe and impurities. In the austenitic stainless steel sheet, the Md30 value which is defined by formula (1) is 0 to 50 DEG C inclusive, the volume ratio of each of a Cr carbide and a Cr nitride is 1% or less, and the average crystal particle diameter of a parent phase is 10 [mu]m or less.
