PROBLEM TO BE SOLVED: To obtain a thermal shrinkable polyolefin tube having good coating workability and excellent in thermostability, flexibility, a coating finishing property and the like. SOLUTION: A thermal shrinkable polyolefin tube consists of elongating a mixed resin composition comprising 60-200 wt.% of a polypropylene polymer (A) wherein a mesotriad percentage (mm) obtained by a 13C-NMR spectrum is 35-75% and a crystalline melting peak temperature (Tm) is not less than 130 deg.C, to 100 pts.wt. of a cyclic olefin polymer (A) wherein a glass transition temperature (Tg) is 50-90 deg.C.
