PROBLEM TO BE SOLVED: To provide a thermoplastic resin-coated FRP cable wherein the thickness of the thermoplastic resin-coated FRP cable used, for example, as a tension member for a drop optical cable or the like is made thin to reduce the outside diameter, and a method manufacturing the same. SOLUTION: The thermoplastic resin-coated FRP cable 6 is formed by impregnating a reinforcing fiber 11 bundle comprising an organic synthetic fiber with an uncured thermosetting resin composition and drawing into a prescribed shape to obtain the cable, forming a coating layer comprising a thermoplastic resin on the outer peripheral surface of the cable, cooling and solidifying the coating layer, curing the thermosetting resin and then adjusting the outer diameter of the coating layer. The uncured thermosetting resin composition contains 0.5-3 pts.mass based on 100 pts.mass thermosetting resin and has excellent bucking resistance. COPYRIGHT: (C)2009,JPO&INPIT
