The invention provides a molded wire and a molded cable, and a wire for a molded wire and a cable for a molded cable. The molded wire and the molded cable have high treatability, high terminal processing property, high gas tightness, high heat resistance and high mechanical strength. The molded cable (110) comprises a conductor (1), an insulation inner layer (2), an insulation outer layer (3), and a resin molded body (30). The insulation inner layer (2) comprises a crosslinked the ethylene resin composition and is provided an outer circumference of the conductor (1). The insulation outer layer (3) comprises a crosslinked thermoplastic polyurethane composition and is provided on an outer circumference of the insulation inner layer (2). Arithmetic average roughness (Ra) of a surface of the insulation outer layer (3) is 5-100 mu m. The resin molded body (30) coats an exposed end portion of the conductor (1) and an end portion of the insulation outer layer (3) at a side of the exposed end portion of the conductor (1). The resin molded body (30) is fused to the insulation outer layer (3). The gel fraction of the ethylene resin composition is more than 45% and the gel fraction of the thermoplastic polyurethane composition is less than 71%.
