Heat-shrinkable tube, heat-shrinkable cap, and method of waterproofing electrical wire bundle

A heat-shrinkable tube or heat-shrinkable cap includes an adhesive layer disposed on the inner surface thereof, the adhesive layer including a low-viscosity adhesive layer formed of a resin having a viscosity of 10 Pa.Math.s or less at a shear rate of 1 s.sup.1 at the heat shrinkage temperature and a viscosity of 100 Pa.Math.s or more at a shear rate of 1 s.sup.1 at the maximum continuous use temperature. The heat-shrinkable tube or heat-shrinkable cap is used for waterproofing an exposed portion of electrical wires of an electrical wire bundle such as a wire harness, in which merely by placing the heat-shrinkable tube or heat-shrinkable cap over the exposed portion of electrical wires, waterproofing and water blocking between strands can be achieved, and outflow of the resin during heat shrinking does not occur. A method of waterproofing an electrical wire bundle uses the heat-shrinkable tube or heat-shrinkable cap.
