Heat-shrinkable tube having tearable properties

A heat-shrinkable tube having tearability comprising at least a melt-processable fluororesin, wherein

• a strain of the tube is represented as ε, a stress at the strain is represented as σ (MPa), a horizontal axis on a coordinate graph is a strain ε, a vertical axis thereon is a stress σ, and in a mechanical property curve of the tube obtained through a measurement method comprising a tensile test being performed under conditions of an ambient temperature of 60° C., an initial chuck-to-chuck distance of 22±0.05 mm, and a tensile speed of 5 mm/sec., the stress σ at the strain of 1.0 is 3.2 MPa or more, and
• when a coordinate point at the strain ε of 1.0 on the mechanical property curve is represented as e and a coordinate point at the strain ε of 2.0 on the mechanical property curve is represented as f, a slope of a straight line passing through the coordinate point e and the coordinate point f is 2.4 to 3.0 Mpa.
