A shield sleeve for shielding an electric wire includes a tensile strength fiber that has an approximately circular section and on which a metal-plating layer is formed. A plurality of the tensile strength fibers is braided to form a tubular shape. Braid density of the braided tensile strength fibers is 85% or more and 98% or less and resistance between the braided tensile strength fibers is 0.096 Ω/m or less.
1. A manufacturing method for a shield sleeve comprising:
applying plating pretreatment to a bundle of one or a plurality of tensile strength fibers, each of the plurality of tensile strength fibers having an approximately circular section;
applying metal plating to the bundle of one or a plurality of tensile strength fibers to which the plating pretreatment is applied; and
braiding the bundle of one or a plurality of tensile strength fibers to which metal plating is applied,
wherein the plating pretreatment includes a first process of applying an oil agent which can dissolve and reduce organo-metallic complex to the one or a plurality of tensile strength fibers, and a second process of contacting a supercritical carbon dioxide to the one or a plurality of tensile strength fibers to which the oil agent is applied in the first step in a state that the organo-metallic complex is charged.
