The present invention provides a polyphenylene sulfide-based heat-shrinkable tube that satisfies the characteristics required for a heat-shrinkable tube, such as heat resistance, low-temperature shrinkage, electrical properties, chemical resistance, and electrolyte resistance. In a heat-shrinkable polyphenylene sulfide-based tube, a resin composition (A) composed of a thermoplastic polyphenylene sulfide-based resin (a) is a main component, and a cold measured by a differential scanning calorimeter according to JIS-K7121. The difference between the crystallization temperature Tc and the similarly measured glass transition temperature Tg is 35 ° C. or more, and the Tg is in the range of 65 ° C. to 85 ° C.
