PROBLEM TO BE SOLVED : To provide a patch transfer medium which can easily transfer a patch to a transfer object, is excellent in security properties to a transferred medium and durable when used, and has a fluorescence emitting fluorescence layer excellent in heat resistance and light resistance in addition to abrasion resistance, solvent resistance, etc., for protecting the surface of the medium and a forgery preventing medium using it. SOLUTION : The patch transfer medium comprises a transfer material 10 (1) composed of a transparent substrate 11, a fluorescence layer 15, and an adhesive layer 19 and a support material 30 (2) in which a peelable resin layer 33 is attached to a support substrate 31. The transfer part of the transfer material 10 is subjected to half cut treatment to make a patch 21, and the patch 21 is laminated peelably on the peelable resin layer 33 surface of the support material 30. The fluorescence layer contains an ionizing radiation curing resin and a fluorescence emitting rare earth complex, and the absorption wavelength range of the ionizing radiation curing resin is different from the absorption wavelength range of the fluorescence emitting rare earth complex.
