<P>PROBLEM TO BE SOLVED: To provide a shrink tube having good covering performance, which can be used without pre-inserting. <P>SOLUTION: The tube is molded by extrusion molding of molding material and the obtained tube is heated and expanded. A high temperature heated region which is heated at relatively high temperature is formed by biasing heating temperature in a circumferential direction of the tube when heating the tube. Thereby, a thin wall is formed so as to extend over the entire longitudinal direction of the expanded tube. A slit is formed in the thin wall of the expanded tube so as to extend over the entire longitudinal direction of the tube and the shrink tube 13 with slit is obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
