Abstract: There are provided a rope which is excellent in a wear resistance and a bending resistance, and a manufacturing method of implementing the rope.A rope (1) including a yarn twisted by using a raw thread (5) of a polyethylene fiber (6) having an ultrahigh molecular weight and a strand (2) twisted by the yarn and subjected to steel-making through the strand (2), and a resin coating layer for protecting the rope (1) is formed on an external surface of the yarn, an external surface of the strand (2) or an external surface of the rope (1). A method of manufacturing the rope (1) includes a pretreating step I of removing an oil content contained in the rope (1) and performing an affinity enhancing treatment over a surface thereof and a resin coating step II of forming a resin coating layer for protecting the rope (1) on an external surface of the yarn, an external surface of the strand (2) or an external surface of the rope (1). The resin coating layer for protecting the rope (1) is formed. For this reason, impurities such as sand in the sea or the like is prevented from intruding into an inner part of the rope (1). Therefore, a life of the rope (1) can be enhanced.
