A composite power cable includes an elongated cable core having an electrical conductor and a shield layer of a semiconductive material. The cable includes an outer sheath of a first thermoplastic resin encompassing the cable core. A plurality of concentric neutral wires are embedded in the outer sheath and helically wound around the cable core. At least one elongated flexible optical fiber unit is embedded in the outer sheath and helically wound around the cable core so as to extend along the neutral wires. The fiber unit includes an elongated body of a second thermoplastic resin extending longitudinally thereof, at least one flexible tube embedded in the body to extend longitudinally thereof, at least one optical fiber loosely received in the tube to extend longitudinally thereof and at least one elongated tension member embedded in the body to extend longitudinally thereof. The second thermoplastic resin is different from the first thermoplastic resin and has non-adhesive property with respect to the first thermoplastic resin.
