1. A leaky coaxial cable comprising:
a central conductor; an insulator covering the central conductor; an external conductor wound around the insulator, having a thickness of 5 μm to 44 μm, and including a plurality of slots formed periodically in a longitudinal direction of the cable; a plastic film attached to the external conductor and having a thickness of 5 μm to 36 μm; and an outer sheath covering the external conductor and the plastic film, wherein the plastic film is attached to a surface of the external conductor facing the outer sheath, the external conductor has a width that forms an overlapping portion in which ends of the external conductor overlap and contact with each other when the external conductor is wound around the insulator, the width of the external conductor is longer by 2 mm to 10 mm than an outer peripheral length of the insulator, and edges of the slots bite a surface of the insulator. |
