Abstract
A metal layer uniform in thickness is formed by electroless plating on both of inner and outer surfaces of a corrugated tube to thereby produce a shield-plated corrugated tube which has a satisfactory flexibility as well as a superior electromagnetically shielding effect. Specifically, in the corrugated tube of resin, at least the size and shape of groove portions inside the tube for forming the convex-concave portions of the tube wall are set to satisfy the condition of 0.5<D/W<1.6 where D represents the depth of each groove portion in the radial direction of the tube and W represents the width of each groove portion in the axial direction of the tube. The metal layers are formed on the inner and outer surfaces of the corrugated tube by electroless plating.
