PROBLEM TO BE SOLVED: To provide a method of manufacturing a roller-shape object, capable of achieving high productivity and excellent machining efficiency and easy to correspond to a design change, while accurately forming the shape of both ends of a resin layer, and to provide a roller-shape object possible to be manufactured by this method. SOLUTION: This method of manufacturing a roller-shape object is characterized by having following processes in order: a first machining process for simultaneously forming a first small-diameter part, which has an equal diameter to a step part, a chamfered part adjacent to the first small-diameter part and formed to be gradually narrowed as it comes from the first small-diameter part, and a second small-diameter part adjacent to the chamfered part and having a diameter equal to the minimum diameter of the chamfered part by using a first cutting tool in both ends of a resin layer body of a resin layer body formed intermediate object formed with the resin layer body in a side surface of a metal shaft; and a second machining process for cutting a part of the second small-diameter part, which is separated from the chamfered part, to the metal shaft by using a second cutting tool for cross-machining.
