Provided is a cable including a stranded member floating-preventing element that can be easily peeled off.

A power transmission line core includes one core member and six side members twisted around the core member, each member obtained by impregnating a fiber bundle including a plurality of carbon fibers that are continuous in the longitudinal direction and bundled into the fiber bundle with a resin and curing the resin. A tow including a plurality of tow fibers that are continuous in the longitudinal direction and arranged flatly and densely is spirally wound around the surface of the power transmission line core in the direction opposite to the twisting direction of the side members. The tow is detachably entangled in the unevenness on the surface of the power transmission line core.
