An injection-molded wire harness and a molding method. The wire harness comprises a terminal (1) and at least one conductor (2); one end of the terminal (1) is connected to an electrical loop of an electric device, and the other end of the terminal (1) is connected to the conductor (2); the wire harness is provided with a protection layer (7) which is formed by injection molding and wraps the conductor (2), and at least one positioning device (5) which is formed by injection molding and is used for fixing the position of the wire harness or/and a sealing device (4) for waterproofing. According to the method, manual operations can be reduced, the consistency of wire harness products is improved, the production cost of the wire harness products is reduced, and the service life of the wire harness is prolonged.
