Abstract

The heat-recoverable article according to the present invention has a cylindrical shape and includes a base material layer. The base material layer contains a polyolefin-based resin. In the base material layer after being heated at 180° C. for 2 minutes, a melting-point peak temperature is 115° C. or higher and 128° C. or lower, a heat of fusion of a total resin component is 80 J/g or more and 150 J/g or less, a storage modulus at 120° C. is 4 MPa or more, a gel fraction is 40% by mass or more and 80% by mass or less, and a storage modulus at 180° C. is 0.5 MPa or more and less than 3.0 MPa. The polyolefin-based resin is preferably a mixture of a first polyolefin-based resin having a melting point of 125° C. or higher and 135° C. or lower and a second polyolefin-based resin having a melting point of lower than 125° C.
