Provided is an in-wheel motor power cable in which a cross-sectional area of a conductor portion can be sufficiently assured for allowing large current to pass therethrough while avoiding excessively large maximum diameter of the cable. The power cable includes a conductor portion; an insulator configured to cover an outer circumference of the conductor portion; a hollow shield wire configured to cover an outer circumference of the insulator; and a sheath configured to cover an outer circumference of the shield wire. The conductor portion comprises a composite strand obtained by stranding a plurality of wire strands each of which is a strand of a plurality of filaments with no insulating layer, each filament being a tin-plated soft copper wire. The insulator is a soft fluororesin, and the shield wire is a braided copper-foiled yarn cable.
