There are many materials used for electromagnetic shielding, one of which is a tape-shaped shielding tape, and a typical example is a tape-shaped foil made of copper, aluminum, or the like. In addition to such metal tape foils, there are also tapes with a conductive film formed on the base tape by metal plating, thermal spraying, etc., and shield tapes obtained by paper-making metal fibers and other conductive fibers. A common problem with shield tapes is that they lack elasticity in the longitudinal direction.

Shielding tape that is not stretchable in the longitudinal direction requires accurate adjustment of the degree of wrapping when wrapping it around the pipe, and if the diameter of the pipe changes, it should be wrapped to avoid wrinkles. Therefore, there is a need to develop a shielding tape that has electromagnetic shielding properties and is stretchable in the longitudinal direction.

Figures 1 and 2 schematically show the structure of the shield tape of the present invention, where a is a plan view of the shield tape and b is a cross-sectional view thereof. It is made of a film-like material, and may or may not be conductive. Most commonly, a soft vinyl chloride film is used. The conductive fibers 3 are arranged in a crosswise orientation (90° in FIG. 1, ±45° in FIG. 2) with respect to the longitudinal direction 2 of the base tape 1. In this invention, conductive fiber 3
exists as a layer in the form of single fibers, but this layer may be buried inside the base tape 1 or may be laminated to the base tape 1 with another substance interposed therebetween.
