Summary:To provide a coaxial cable that barely causes sudden attenuation in a predetermined frequency band and has a reduced loss.SOLUTION: A coaxial cable 1 comprises a conductor 2, an insulator 3 that covers the outer face of the conductor 2, a shield layer 4 that covers the outer face of the insulator 3, and a sheath 5 that covers the outer face of the shield layer 4. The shield layer 4 comprises a spiral shield part 41 in which metal strands 411 being elliptical in a cross section perpendicular to a longitudinal direction are spirally wound around the insulator 3, and a collective plating part 42 that covers the outer face of the spiral shield part 41 and is composed of conductive plating.SELECTED DRAWING: Figure 1 【課題】所定の周波数帯域で急激な減衰が生じにくく、かつ、損失を低減した同軸ケーブルを提供する。【解決手段】同軸ケーブル１は、導体２と、導体２の周囲を覆う絶縁体３と、絶縁体３の周囲を覆うシールド層４と、シールド層４の周囲を覆うシース５と、を備え、シールド層４は、長手方向に垂直な断面の形状が楕円である複数の金属素線４１１を絶縁体３の周囲に螺旋状に巻き付けて構成された横巻きシールド部４１と、横巻きシールド部４１の周囲を覆う導電性のめっきからなる一括めっき部４２と、を有する。【選択図】図１
