Provided are a decorative film in which the formation of wrinkles when applied to a three-dimensional molded article in an elongated state is suppressed, a method for manufacturing a decorative film,a method for manufacturing a three-dimensional molded article comprising a decorative film, and a fluorine-containing polymer composition. This decorative film comprises at least a substrate film layer and a fluorine-containing layer containing a cross-linked fluorine polymer, wherein: the cross-linked fluorine-containing polymer is a cross-linked product of a cross-linkable polymer containing a fluoroolefin-based unit and a unit comprising a cross-linkable group; and the cross-linked fluorine-containing polymer has an average inter-cross-link molecular weight of 500-50,000. 提供：以拉伸后的状态贴接于三维成形品时，褶皱的产生得以抑制的装饰薄膜、装饰薄膜的制造方法、带装饰薄膜的三维成形品的制造方法及含氟聚合物组合物。本发明的装饰薄膜至少具有：基材薄膜层、包含交联含氟聚合物的含氟层，上述交联含氟聚合物为：包含基于氟烯烃的单元及具有交联性基团的单元的交联性的聚合物的交联物，上述交联含氟聚合物的平均交联点间分子量为500～50,000。
