Provided is a covering material, in which the covering material is a covering material for covering a superconducting wire, a tensile strength at break thereof at −196° C. is 12.0 N/3 mm or more, and a tensile elongation at break thereof at −196° C. is 12% or more. The covering material preferably includes a backing made of a polyimide resin. The covering material preferably includes a viscoelastic layer formed on one surface of the backing. |
