Abstract
A coaxial cable includes an inner conductor, an insulation covering the inner conductor, an outer conductor covering the insulation, and a sheath covering the outer conductor. The inner conductor is a compressed conductor including a central element wire and multiple peripheral element wires surrounding the central element wire. The inner conductor has a compressibility of 23.0% or more and 35.0% or less in percentage. The compressibility is calculated from a sectional area S1 and the sectional area S2 of the compressed conductor by Compressibility=[1−S2/S1]. The sectional area S1 is calculated from the outside diameter D of the central element wire and the total number n of the central and peripheral element wires by S1=n×π×0.25×D. The outside diameter of the insulation is 1.25 mm or more and less than 1.75 mm.
