Abstract
A coaxial cable includes an inner conductor; an insulator covering a circumference of the inner conductor; a shield layer covering a circumference of the insulator; and a sheath covering a circumference of the shield layer. The inner conductor is composed of first metal strands that are twisted each other in such a manner that a cross-sectional shape of the inner conductor is circular. The shield layer includes a winding shield layer including second metal strands spirally wound around the insulator, and a shield tape layer including a shield tape including a resin tape and a metal layer provided on one side of the resin tape, the shield tape being spirally wound around the winding shield layer with the metal layer being located inwardly radially in such a manner that the metal layer is being in contact with the winding shield layer. The winding shield layer has a gap in at least one location between the second metal strands adjacent to each other in a circumferential direction, and a sum of distances w between the second metal strands adjacent to each other via the gap is not more than an outer diameter d of the second metal strand in a cross-section perpendicular to a longitudinal direction.
