PROBLEM TO BE SOLVED: To provide a component for transferring a water-insoluble polymer thin film, which, when applied on an application object, can stably transfer only the water-insoluble polymer thin film on a surface of an application object by easily separating a substrate from the water-insoluble polymer thin film adhered on the surface of the application object, and to provide a method for producing the same.SOLUTION: Provided is a component and the like for transferring a water-insoluble polymer thin film, comprising a water-insoluble polymer thin film to be transferred to an adherend and a substrate to support the water-insoluble polymer thin film which are laminated. Film thickness of the water-insoluble polymer thin film is set at a value in a range of 20 to 500 nm and film thickness of the substrate is set at a value in a range of 1 to 1,000 μm. Further, a contact area ratio of the water-insoluble thin film and the substrate is set at a value in a range of 20 to 80% relative to 100% of an area
