PROBLEM TO BE SOLVED: To provide a heat-shrinkable tubular label which is a heat insulation label and is exactly subjected to shrink fitting without causing warping to the outside. SOLUTION: The heat-shrinkable tubular label is constituted in such a manner that a label base material 5 prepared by laminating heat-shrinkable film layers 3, 4 on both surfaces of a non-woven fabric 2 is formed in a tubular shape and the rate of thermal shrinkage of inner side heat-shrinkable film layer 4 is equal to or is larger than the rate of thermal shrinkage of outer side heat-shrinkage film layer 3. A center seal part is constituted in such a manner that a side edge part 5b of the inner side heat-shrinkable film layer 4 is overlapped on a side edge part 5a of the outer side heat-shrinkable film layer 3 and the overlapped parts are bonded by using a solvent.
