A coaxial cable includes an inner conductor having one center wire, and six outer wires stranded around the center wire, an insulator covering an outer periphery of the inner conductor, and a shield conductor covering an outer periphery of the insulator, wherein, in a cross section perpendicular to a longitudinal direction of the coaxial cable, a ratio of a total area of first regions which are respectively formed by a gap between the center wire and two adjacent outer wires, with respect to an area of a circumscribed circle of the inner conductor, is 0.5% or higher and 2.0% or lower, and a ratio of a total area of second regions which are respectively formed by a gap between surfaces of the two adjacent outer wires and a surface of the insulator, with respect to the area of the circumscribed circle of the inner conductor, is 2.0% or higher and 5.0% or lower.
