PROBLEM TO BE SOLVED: To provide a method for manufacturing bars and wires by which direct rolling is possible as it is cast without executing preprocessing for recrystallization, cost and time used for the conventional blooming or the like are omitted and the efficiency of the rolling is rapidly improved about hot hard-to-work kinds of steel of austenitic stainless steel. SOLUTION: This method is a method for manufacturing the bars and wires by executing slight rolling of a cast billet of austenitic stainless steel having a circular cross section by skew rolling after heating in a cast billet heating stage and, next, caliber rolling. In this manufacturing method of the bars and wires of austenitic stainless steel, the skew rolling is executed at the outer layer reduction ratio so that the reduction ratio of the outer layer of steel per roll is >=15% in the skew rolling and average number of roll contact.
