To provide a power cable longitudinally attached with at least a metallic foil layer in a water-shield structure.

The power cable 100A provided with a water-shield structure under a sheath 110 has at least a corrugated metal foil layer 224 lengthwise in the water-shield structure. Owing to the corrugated shape of this metal foil layer 224, flexibility gets large, tolerance for bending of the cable is large, fear for damage is largely reduced, width of optimum temperature condition at adhesion can be set widely as well, and such a merit can also be obtained as extrusion temperature getting easily controlled or the like.
