To provide an electric power cable line that can decrease the number of connections of cables, and reduce a voltage induced in a shield metal layer of a cable.

There is provided an electric power cable line 10 to which a plurality of cables 11 each having a shield metal layer are connected and which transmits three-phase AC electric power. The plurality of cables 11 are connected by insulation connection parts 12 which insulates shield metal layers, and the insulation connection parts 12 make cross-bond connections of the shield metal layers. The plurality of cables 11 have lengths set so that, on a complex plane having a reference potential at an origin and includes one axis as a real-number axis and the other axis as an imaginary axis, the center of a circumscribed circle of a figure that induced voltage vectors of the shield metal layers of the plurality of shield metal layers draw meets the origin substantially .
