Abstract: The invention offers a submarine solid cable that can suppress the movement of the insulating oil when the cable is used and the production method thereof. The method of producing a submarine solid cable forms an insulating layer by lapping insulating tapes, each of which includes a resin film, over the outer circumference of a conductor and impregnates the insulating layer with medium-viscosity insulating oil. The insulating layer is formed by lapping insulating tapes, each of which includes a resin film, over the outer circumference of the conductor 1. The insulating layer is impregnated with an insulating oil having an at least medium viscosity. The resin film is swelled to narrow an impregnation path impregnated with the insulating oil. According to the production method, the impregnation path for the insulating oil is secured when the impregnation with the insulating oil is performed and the impregnation path is narrowed to suppress the movement of insulating oil when the cable is used.
