A rope including a yarn twisted by using a raw thread of a polyethylene fiber having an ultrahigh molecular weight and a strand twisted by the yarn and subjected to rope-making through the strand, and a resin coating layer for protecting the rope is formed on an external surface of the yarn, an external surface of the strand or an external surface of the rope. A method of manufacturing the rope includes a pretreating step I of removing an oil content contained in the rope 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 on an external surface of the yarn, an external surface of the strand or an external surface of the rope. The resin coating layer for protecting the rope is formed.
