PROBLEM TO BE SOLVED: To provide a method for producing a shrink molding, where a shrink molding having a desired projecting shape can be formed even if a molding die does not have a complicated structure, and the shrink molding can be easily drawn out from the molding die. SOLUTION: The method for producing the shrink molding having a projecting shape formed at the outer face, includes: a step where a cylindrical sheet 5 which has a thermal-shrinkable sheet formed in a cylindrical shape and a shrinkage regulation member 2 regulating thermal shrinkage, added to a part of the inner face is externally inserted into a molding die 8; a step where the cylindrical sheet 5 is heated at a thermal shrinkage temperature, thus the cylindrical sheet 5 is thermally shrunk along the molding die 8, so as to obtain a shrunk molding; and a step where the shrink molding is drawn out from the molding die 2.
