PROBLEM TO BE SOLVED: To provide the manufacturing method of a slide rail capable of obtaining the new track of a drawer differently from the conventional slide rail by which the track of the drawer becomes straight. SOLUTION: A linearly extended outer rail 1 is prepared, and a plurality of rolls 31, 32, and 33 of parallel shafts are used. The linearly extended outer rail 1 is made to pass through the rolls 31, 32, and 33 by the rotation of the rolls 31, 32, and 33 and the outer rail 1 is bent in a circular arcuate shape. A linearly extended inner rail 2 is prepared and the plurality of rolls 31, 32, and 33 of the parallel shafts are used. The linearly extended inner rail 2 is made to pass through the rolls 31, 32, and 33 by the rotation of the rolls 31, 32, and 33 and the inner rail 2 is bent in the circular arcuate shape.
